If a commit fails to pass the test suite then it would be rejected and never committed to the main repository, preventing it from causing issues with other developers. If a commit passes then the buildbots could automagically push the changes into the main repository.

FWIW, I set up a system like this for another project a few years
ago (using Hudson (now Jenkins) instead of Buildbot).  As far as
I know, the team is still using this system successfully to manage
their changes. 

Jenkins' git plugin has built-in support for this scenario (the
"Push Merges back to origin" option).  I have no idea how difficult
this would be to implement for Buildbot, and I haven't heard of
anyone actually doing it.

I'm not by any means advocating that we switch to Jenkins... just
mentioning my experience.
