+/* 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).
