Reverting is simple. You just comment out the bot in zorg/buildbot/llvmlab/master/config/builders.py,
but you need to notify Galina to trigger a builbot restart. So there is one day latency.
So just reverting buildbots needs some time. I generally try to inform the owner. If the bot is red for two days,
I disable it and inform the mailing list. (This does not happen very often).
