By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Library General +Public License instead of this License. diff --git a/ChangeLog b/ChangeLog new file mode 100644 index 0000000..f1814bf --- /dev/null +++

Note that such code is very difficult to get + right, and will unavoidably be less portable than lock-based code. It + is also not always faster than lock-based code. But it may occasionally + be a large performance win. + +* To experiment with new and much better thread programming paradigms, etc. + +For details and licensing restrictions see the files in the "doc" +subdirectory. + + +## Installation and Usage + +The configuration and build scripts for this package were generated by +Automake/Autoconf. `./configure; make; sudo make install` in this +directory should work. For a more customized build, see the output of +`./configure --help`. To build it from the development repository, +`./autogen.sh` should be executed first. + +Note that much of the content of this library is in the header files. +However, two small libraries are built and installed: + +* `libatomic_ops.a` is a support library, which is not needed on some + platforms. This is intended to be usable, under some mild restrictions, + in free or proprietary code, as are all the header files. + See doc/LICENSING.txt. + +* `libatomic_ops_gpl.a` contains some higher level facilities. This code is + currently covered by the GPL. The contents currently correspond to + the headers `atomic_ops_stack.h` and `atomic_ops_malloc.h`. + + +## Platform Specific Notes + +Win32/64: src/Makefile.msft contains a very simple Makefile for building +and running tests and building the gpl library. The core `libatomic_ops` +implementation is entirely in header files. + +HP-UX/PA-RISC: `aCC -Ae` won't work as a C compiler, since it doesn't support +inline assembly code.

It is sometimes +necessary, and always recommended to also link against libatomic_ops.a. +To use the almost non-blocking stack or malloc implementations, +see the corresponding README files, and also link against libatomic_gpl.a +before linking against libatomic_ops.a. + +OVERVIEW: +Atomic_ops.h defines a large collection of operations, each one of which is +a combination of an (optional) atomic memory operation, and a memory barrier. +Also defines associated feature-test macros to determine whether a particular +operation is available on the current target hardware (either directly or +by synthesis). This is an attempt to replace various existing files with +similar goals, since they usually do not handle differences in memory +barrier styles with sufficient generality. + +If this is included after defining AO_REQUIRE_CAS, then the package makes +an attempt to emulate AO_compare_and_swap* (single-width) in a way that (at +least on Linux) should still be async-signal-safe. As a result, most other +atomic operations will then be defined using the compare-and-swap +emulation. This emulation is slow, since it needs to disable signals. +And it needs to block in case of contention. If you care about performance +on a platform that can't directly provide compare-and-swap, there are +probably better alternatives. But this allows easy ports to some such +platforms (e.g. PA_RISC). The option is ignored if compare-and-swap +can be implemented directly. + +If atomic_ops.h is included after defining AO_USE_PTHREAD_DEFS, then all +atomic operations will be emulated with pthread locking. This is NOT +async-signal-safe. And it is slow. It is intended primarily for debugging +of the atomic_ops package itself. + +Note that the implementation reflects our understanding of real processor +behavior. This occasionally diverges from the documented behavior. (E.g. +the documented X86 behavior seems to be weak enough that it is impractical +to use. Current real implementations appear to be much better behaved.) +We of course are in no position to guarantee that future processors +(even HPs) will continue to behave this way, though we hope they will. + +This is a work in progress. Corrections/additions for other platforms are +greatly appreciated. It passes rudimentary tests on X86, Itanium, and +Alpha. + +OPERATIONS: + +Most operations operate on values of type AO_t, which are unsigned integers +whose size matches that of pointers on the given architecture. Exceptions +are: + +- AO_test_and_set operates on AO_TS_t, which is whatever size the hardware +supports with good performance. In some cases this is the length of a cache +line. In some cases it is a byte. In many cases it is equivalent to AO_t. + +- A few operations are implemented on smaller or larger size integers. +Such operations are indicated by the appropriate prefix: + +AO_char_... Operates on unsigned char values. +AO_short_... Operates on unsigned short values. +AO_int_... Operates on unsigned int values. + +(Currently a very limited selection of these is implemented. We're +working on it.) + +The defined operations are all of the form AO_[_](). + +The component specifies an atomic memory operation. It may be +one of the following, where the corresponding argument and result types +are also specified: + +void nop() + No atomic operation. The barrier may still be useful. +AO_t load(const volatile AO_t * addr) + Atomic load of *addr. +void store(volatile AO_t * addr, AO_t new_val) + Atomically store new_val to *addr. +AO_t fetch_and_add(volatile AO_t *addr, AO_t incr) + Atomically add incr to *addr, and return the original value of *addr. +AO_t fetch_and_add1(volatile AO_t *addr) + Equivalent to AO_fetch_and_add(addr, 1). +AO_t fetch_and_sub1(volatile AO_t *addr) + Equivalent to AO_fetch_and_add(addr, (AO_t)(-1)). +void and(volatile AO_t *addr, AO_t value) + Atomically 'and' value into *addr. +void or(volatile AO_t *addr, AO_t value) + Atomically 'or' value into *addr. +void xor(volatile AO_t *addr, AO_t value) + Atomically 'xor' value into *addr. +int compare_and_swap(volatile AO_t * addr, AO_t old_val, AO_t new_val) + Atomically compare *addr to old_val, and replace *addr by new_val + if the first comparison succeeds. Returns nonzero if the comparison + succeeded and *addr was updated. +AO_t fetch_compare_and_swap(volatile AO_t * addr, AO_t old_val, AO_t new_val) + Atomically compare *addr to old_val, and replace *addr by new_val + if the first comparison succeeds; returns the original value of *addr. +AO_TS_VAL_t test_and_set(volatile AO_TS_t * addr) + Atomically read the binary value at *addr, and set it. AO_TS_VAL_t + is an enumeration type which includes two values AO_TS_SET and + AO_TS_CLEAR. An AO_TS_t location is capable of holding an + AO_TS_VAL_t, but may be much larger, as dictated by hardware + constraints. Test_and_set logically sets the value to AO_TS_SET. + It may be reset to AO_TS_CLEAR with the AO_CLEAR(AO_TS_t *) macro. + AO_TS_t locations should be initialized to AO_TS_INITIALIZER. + The values of AO_TS_SET and AO_TS_CLEAR are hardware dependent. + (On PA-RISC, AO_TS_SET is zero!) + +Test_and_set is a more limited version of compare_and_swap. Its only +advantage is that it is more easily implementable on some hardware. It +should thus be used if only binary test-and-set functionality is needed. + +If available, we also provide compare_and_swap operations that operate +on wider values. Since standard data types for double width values +may not be available, these explicitly take pairs of arguments for the +new and/or old value. Unfortunately, there are two common variants, +neither of which can easily and efficiently emulate the other. +The first performs a comparison against the entire value being replaced, +where the second replaces a double-width replacement, but performs +a single-width comparison: + +int compare_double_and_swap_double(volatile AO_double_t * addr, + AO_t old_val1, AO_t old_val2, + AO_t new_val1, AO_t new_val2); + +int compare_and_swap_double(volatile AO_double_t * addr, + AO_t old_val1, + AO_t new_val1, AO_t new_val2); + +where AO_double_t is a structure containing AO_val1 and AO_val2 fields, +both of type AO_t. For compare_and_swap_double, we compare against +the val1 field. AO_double_t exists only if AO_HAVE_double_t +is defined. + +Please note that AO_double_t (and AO_stack_t) variables should be properly +aligned (8-byte alignment on 32-bit targets, 16-byte alignment on 64-bit ones) +otherwise the behavior of a double-wide atomic primitive might be undefined +(or an assertion violation might occur) if such a misaligned variable is +passed (as a reference) to the primitive. Global and static variables should +already have proper alignment automatically but automatic variables (i.e. +located on the stack) might be misaligned because the stack might be +word-aligned (e.g. 4-byte stack alignment is the default one for x86). +Luckily, stack-allocated AO variables is a rare case in practice. + +ORDERING CONSTRAINTS: + +Each operation name also includes a suffix that specifies the associated +ordering semantics. The ordering constraint limits reordering of this +operation with respect to other atomic operations and ordinary memory +references. The current implementation assumes that all memory references +are to ordinary cacheable memory; the ordering guarantee is with respect +to other threads or processes, not I/O devices. (Whether or not this +distinction is important is platform-dependent.) + +Ordering suffixes are one of the following: + +: No memory barrier. A plain AO_nop() really does nothing. +_release: Earlier operations must become visible to other threads + before the atomic operation. +_acquire: Later operations must become visible after this operation. +_read: Subsequent reads must become visible after reads included in + the atomic operation or preceding it. Rarely useful for clients? +_write: Earlier writes become visible before writes during or after + the atomic operation. Rarely useful for clients? +_full: The associated operation is ordered with respect to both earlier and + later memory ops. If the associated operation is nop, then this orders + all earlier memory operations with respect to subsequent ones. + AO_store_full or AO_nop_full are the normal ways to force a store + to be ordered with respect to a later load. +_release_write: Ordered with respect to earlier writes. This is + normally implemented as either a _write or _release + barrier. +_acquire_read: Ordered with respect to later reads. This is + normally implemented as either a _read or _acquire barrier. +_dd_acquire_read: Ordered with respect to later reads that are data + dependent on this one. This is needed on + a pointer read, which is later dereferenced to read a + second value, with the expectation that the second + read is ordered after the first one. On most architectures, + this is equivalent to no barrier. (This is very + hard to define precisely. It should probably be avoided. + A major problem is that optimizers tend to try to + eliminate dependencies from the generated code, since + dependencies force the hardware to execute the code + serially.) + +We assume that if a store is data-dependent on a previous load, then +the two are always implicitly ordered. + +It is possible to test whether AO_ is available on the +current platform by checking whether AO_HAVE__ is defined +as a macro. + +Note that we generally don't implement operations that are either +meaningless (e.g. AO_nop_acquire, AO_nop_release) or which appear to +have no clear use (e.g. AO_load_release, AO_store_acquire, AO_load_write, +AO_store_read). On some platforms (e.g. PA-RISC) many operations +will remain undefined unless AO_REQUIRE_CAS is defined before including +the package. + +When typed in the package build directory, the following command +will print operations that are unimplemented on the platform: + +make test_atomic; ./test_atomic + +The following command generates a file "list_atomic.i" containing the +macro expansions of all implemented operations on the platform: + +make list_atomic.i + +Known issues include: + +We should be more precise in defining the semantics of the ordering +constraints, and if and how we can guarantee sequential consistency. + +Dd_acquire_read is very hard or impossible to define in a way that cannot +be invalidated by reasonably standard compiler transformations. + +There is probably no good reason to provide operations on standard +integer types, since those may have the wrong alignment constraints. + + +Example: + +If you want to initialize an object, and then "publish" a pointer to it +in a global location p, such that other threads reading the new value of +p are guaranteed to see an initialized object, it suffices to use +AO_release_write(p, ...) to write the pointer to the object, and to +retrieve it in other threads with AO_acquire_read(p). + +Platform notes: + +All X86: We quietly assume 486 or better. + +Gcc on x86: +Define AO_USE_PENTIUM4_INSTRS to use the Pentium 4 mfence instruction. +Currently this is appears to be of marginal benefit. diff --git a/doc/README_malloc.txt b/doc/README_malloc.txt new file mode 100644 index 0000000..ec4ed89 --- /dev/null +++ b/doc/README_malloc.txt @@ -0,0 +1,57 @@ +The libatomic_ops_gpl includes a simple almost-lock-free malloc implementation. + +This is intended as a safe way to allocate memory from a signal handler, +or to allocate memory in the context of a library that does not know what +thread library it will be used with.
