> [~apurtell] pointed out a potential race condition in RecoverableZookeeper.checkZk()
that I introduced in parent.
> If multiple threads would enter that method at the same time without a valid Zookeeper
reference, we could leak Zookeeper objects.
> Since this is not a on a hot code path we should just synchronize the two involved methods.
