    Description

      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.
