Chris@4:    can compress it reasonably rapidly.  This is to help test
Chris@4:    support for large files (> 2GB) in a reasonable amount of time.
Chris@4:    I suggest you use the undocumented --exponential option to
Chris@4:    bzip2 when compressing the resulting file; this saves a bit of
Chris@4:    time.  Note: *don't* bother with --exponential when compressing 
Chris@4:    Real Files; it'll just waste a lot of CPU time :-)
Chris@4:    (but is otherwise harmless).
