Done.  I agree.  I'll work on automating this.

Having a buildbot is extremely useful for "localizing" breakage to a  
specific change ("temporalizing"?).  I think this might be why it is  
considered so important to have an all-green buildbot -- because then  
if something breaks everyone knows that it was "this change right  
here" that caused the breakage.

But if you don't have an all-green buildbot and so you don't  
necessarily notice right away, you can search backwards through the  
build histories to figure it out, like you just did.
