And even *more* importantly, note that when downloading a -mm or -rc3 patch,
there's minimal server overhead - it opens *one* file and streams it to the
FTP connection. sendfile() anybody? ;)

How many open/close/etc are needed to sync up 2 'git' mirrors? I don't care *how*
stupendous git/mercurial/whatever are, they're going to have a *really* hard time
getting down to the overhead of an FTP session sending a .bz2 file.

Unless of course, there's only me and a dozen other people even *trying* -mm
kernels and the distinction is lost in the noise... (Out of curiosity, how
many downloads *DO* the -mm kernels get? I know Linus and Andrew want more
testing.. let's keep that in mind here.. ;)
