   FYI - I wrote the Curator portions of this new feature as a test. One of them is a new
path cache that replaces Curator's `TreeCache`, `PathChildrenCache` and `NodeCache`. First,
the code is _so_ much simpler and easier to reason about. This alone will reduce errors and
complexity. Also the number of ZK calls needed (and overhead for all those watchers) is vastly
reduced.
   
   I wrote a test to exercise the new cache, include with forced server crashes, and it's
working perfectly. So, this suggest this new Watcher code is good. So, FYI, another data point.
