/* spew out a thoroughly gigantic file designed so that bzip2

   can compress it reasonably rapidly.  This is to help test

   support for large files (> 2GB) in a reasonable amount of time.

   I suggest you use the undocumented --exponential option to

   bzip2 when compressing the resulting file; this saves a bit of

   time.  Note: *don't* bother with --exponential when compressing 

   Real Files; it'll just waste a lot of CPU time :-)

   (but is otherwise harmless).
