The currently-deployed gerrit scheduler code has vanished from the 
author's github repo. I could make it available, but there isn't much 
value in doing so. Currently, there are three implementations of the 
gerrit scheduler:

g1: the currently deployed scheduler, written by Jay Soffian. It was 
written before gerrit had upstream support.
g2: the gerrit scheduler from newer buildbot  versions. This one does 
one gerrit comment per builder...not desirable
g3: a custom version from YFS.

I would like to merge g2 and g3, but I'm waiting for a working config 
file so that I can move forward. This situation is why I haven't 
upgraded the buildbot master software.

What ever is done, should be done after getting a workable gerrit 
scheduler and  upgrading.
