Comment(by dustin):

 You could add some print's in here ({{{buildbot/db/connector.py}}}):
 {{{
  363         q += " ORDER BY changeid DESC"
 --here--
  364         rows = self.runQueryNow(q, tuple(args))
 --here--
  365         # will this work? do I need to finish fetching everything by
 using
  366         # list(rows)? or can I use it as an iterator and fetch things
 as
  367         # needed? will the queries in getChangeNumberedNow()
 interfere with
  368         # that iterator?
 --here--
  369         for (changeid,) in rows:
 --here--
  370             yield self.getChangeNumberedNow(changeid)
 }}}

 I suspect either that line 364 takes forever to execute, or line 369 does.
