For a while I thought this was the perl client not calling zookeeper_close()
properly, but I can reproduce this using the example c_client code from the
twiki as well.
(http://hadoop.apache.org/zookeeper/docs/r3.3.1/zookeeperProgrammers.html#ZooKeeper+C+client+API)
I thought I'd check here before filing a JIRA; am I missing something obvious?
Anytime a client disconnects from my quorum servers, even when
zookeeper_close() has been called, I get this:

I looked through list archives and such, most other occurrences of this have to
do with some other error (bad timeouts, etc). In this case I'm closing the
connection properly and the cluster is working just fine.
