Jordan Zimmerman commented on CURATOR-14:
-----------------------------------------

In DispatchingWatcher, why is the key to the watchers a UUID instead of the ZNode path?

> The JVM runs out of memory if you repetitively create a PathChildrenCache, start it then
immediately stop it.  It appears that the memory is taken up by a watch that isn't ever cleaned
up.  Curator attempts to do some pooling of watches, but doesn't seem to use the path in the
pooling.
