> We ran into a production issue yesterday where the SplitLogManager tried to create a
Rescan node in ZK.  The createAsync() generated a KeeperException.CONNECTIONLOSS that was
immedately sent to processResult(), createRescan node with --retry_count was called, and this
created a CPU busywait that also clogged up the logs.  We should handle this better.
