Subject RE: question about lock recipe and watchers

I am about to implement a locking algorithm based on the below modification to the Zookeeper-website-recommended
one. Does anyone else have experience with this?

Thank you, Michi, for the suggestion below.

You could set the watch using get() instead of exists(). These watches
get set if and only if the znode exists, and they get triggered when
the znode goes away.
