--------------------------------------
[~nspiegelberg], [~stack], [~apurtell] still valid? Perhaps it's worth a

> 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.
