NOTE: depending on its implementation,
InterProcessLock.release() may throw an exception if the current thread does not own the lockA container that manages multiple locks as a single entity.

Abstraction to select a "leader" amongst multiple contenders in a group of JVMs connected to
a Zookeeper cluster.
How to handle listeners when the latch is closed
A LeaderLatchListener can be used to be notified asynchronously about when the state of the LeaderLatch has changed.
