Comment (by dustin):

 In one of the logfiles, Buildbot seems to end up sitting in the reactor
 loop forever

 The first bit is thread 2, pid 357.  It finishes its work (database-y
 stuff), notifies the main thread (by writing an 'x' to a self-pipe), and
 parks itself.  The parent thread gets this byte, then re-enters the select
 loop.
