---------------------------------------
Hi Mahadev,
need to go. short comments:
- I don't see any possible synchronization issues with the patch?
- I really want to go further with the refactoring and want to add the JavaDocs
once we arrive at a state that we all agree on. - Please ignore the javadoc for
now and I promise I'll provide them later.

> ZooKeeper instantiates ClientCnxn in its ctor with this and therefor builds a
> cyclic dependency graph between both objects. This means, you can't have the
> one without the other. So why did you bother do make them to separate classes
> in the first place?
> ClientCnxn accesses ZooKeeper.state. State should rather be a property of
> ClientCnxn. And ClientCnxn accesses zooKeeper.get???Watches() in its method
> primeConnection(). I've not yet checked, how this dependency should be
> resolved better.
