Patrick Hunt updated ZOOKEEPER-1433:
------------------------------------
Attachment: ZOOKEEPER-1433.patch
This patch fixes the issue. Went from being able to reproduce the flakey test
issue on particular hardware once every 10 runs to running more than 100 runs
without seeing it again. Getting the client connection handling right turned
out to be tricky.
