Patrick Hunt commented on ZOOKEEPER-442:
----------------------------------------

[~rakeshr] just to make sure I'm understanding correctly, the document you put 
together is based on the current approach/patch, is that right? Or are you 
suggesting a different implementation? (my quick perusal indicates the former 
but I want to make sure I'm not missing something)

> need a way to remove watches that are no longer of interest

> currently the only way a watch cleared is to trigger it. we need a way to 
> enumerate the outstanding watch objects, find watch events the objects are 
> watching for, and remove interests in an event.
