/* 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).
