Reconfig tends to work pretty well with simple configs, but the more
modifications, the worse things get.  Python's `reload()` has lots of
known problems with e.g., redefining new classes with the same name as
old, for one thing.

There is a "clean shutdown" option for the master which allows all
running builds to finish but does not accept new jobs.

Regarding the failures you've seen, nothing jumps to mind.

If you can narrow down the circumstances in which slaves get stuck, we
might be able to find the bug.
