Hi Olivier,

Zookeeper connections are pooled, so they are pulled out of the pool at
will by ManifoldCF and returned when the lock etc is done.  This means you
really should need only a total number of outstanding Zookeeper handles
that is on the same order as the number of operating threads in your
ManifoldCF cluster.  We do have some users, though, who have hundreds of
worker threads in the mistaken assumption that more threads makes the
system faster, and when people do stuff like that, we often get tickets
because the number of zookeeper handles runs out.  That is why there is
such a large number.
