> Zookeeper client using zkpython segfaults on zookeeper server restart. It is reliably reproducible using the attached script zk.py.
> I'm able to stop segfault using the attached patch voyager.patch, but zkpython seems to have deeper issue on its use of watcher_dispatch - on zookeeper server restart, I see up to 6 invocation of watcher_dispatch while my script is simply sleeping in the main thread. This can't be right.
