Robert Joseph Evans commented on STORM-70:
------------------------------------------

There appear to be two different things happening.  On Linux things are just 
generally a bit slower.  Not totally sure why, but everything still works.  On 
Mac, however, there appears to be some sort of a timeout that is happening some 
of the time when a new curator instance is created.  On my mac about 4 out of 
10 new curator instances will have almost exactly a 5 second delay before the 
curator client's first command can be processed.

This is specifically a ZK issue, because zk-3.3.6 is always very fast, but 
zk-3.4.0 shows this, while holding everything else the same.  I need to dig 
into this a bit more, but I thought I would give an update on my progress.

> use zookeeper-3.4.5
