If a commit passes then the buildbots could automagically push the changes into the main repository.

This is definitely possible, and would be cool to see implemented. The
big issue with this, though, is we don't presently have the buildbot
power to isolate individual broken commits and then retest all the
commits depending on them. It wouldn't even need to be a separate
repository; one repo could have an 'incoming' branch and its master
could refuse pushes, and then the repository machine has hooks which
test commits and then fast forward merge them into master once they're
confirmed good.

I do wish we had the buildbot power for this; it would be very useful.
