/* Make the process sleep for SECONDS seconds, or until a signal arrives

   and is not ignored.  The function returns the number of seconds less

   than SECONDS which it actually slept (zero if it slept the full time).

   If a signal handler does a `longjmp' or modifies the handling of the

   SIGALRM signal while inside `sleep' call, the handling of the SIGALRM

   signal afterwards is undefined.  There is no return value to indicate

   error, but if `sleep' returns SECONDS, it probably didn't work.  */
