This sounds like a good optimization, but be aware that as of 0.8.4
you won't be able to do synchronous database queries, and the
waterfall is entirely synchronous.  Which is to say, if you want data
from the database, you will get a deferred back.

No, the web status has not been significantly optimized, but lots of
other stuff has changed.  If you're patching Buildbot itself, I highly
recommend upgrading to the latest release.  You may also want to track
development on 'master', although right now I don't consider master
stable enough to run.
