New description:
Every now and then on 0.8.5 and more often on 0.8.7p1 we see at
reconfigure time:
sending SIGHUP to process 41208
Never saw reconfiguration finish.
The fix is generally to restart the master, but the problem with this
approach is it's going to stop everybody else's builds from happening (we
get slaves lost due to the time it takes to reconfigure - way less than
the 10 minutes timeout, but we lose them still).
Doing $ kill -SIGHUP 41208 doesn't produce anything in twistd.log, so it
appears to be indeed stuck.
How can we make this rock-solid?

Comment (by dustin):
Did you try adding the debugging code in comment 3? That would help to
narrow this down.
