I think that some of the existing `daemon.py` code is unnecessarily
complicated and confusing (see some of my comments at
https://github.com/mesos/spark/pull/563), so I'd like to clean things up before
we add any more code. I'll have a patch for this cleanup by tonight or
tomorrow.
One note: I'm a bit wary of the mixture of fork() and Thread in the same
daemon's forked process; is this safe?
