Ioannis Canellos commented on CURATOR-14:
-----------------------------------------

I think that there is consensus in adding & using an unregister mechanism.
I can work on that once I get back from vacation (2 weeks).

> 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.
