[Python-3000] Python 3.0a2 release

> Job for the win64 buildbot, maybe?

Is it possible to share the profile data across machines?
I would certainly want to build and test the releases on
my own machines, rather than having to rely on a buildbot.
I then rather do a multi-reboot thing where I build the AMD64
profiling binaries, reboot to AMD64 mode, run the binaries,
reboot back to 32-bit mode, build the release, and reboot
again to test the release.

Regards,
Martin
