/* 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).
