Patrick Hunt commented on ZOOKEEPER-220:
----------------------------------------
Comment from Stu on user list:
> It may be better not to let the programmer know about those two
> lists, and to see if the abstraction can be improved instead.
> Sometimes I feel that I have to know too much about the internal
> working of ZooKeeper to use its API.
> programming guide watches section should clarify server/clientlib role in
> data/child watch maint.

> The server is maintaining two lists, it's not really clear in some sections
> that it's the server, esp as in v3 the client is also maintaining it's own
> list(s).
