org.apache.curator.framework.recipes.locks.InterProcessMutex
A re-entrant mutex that works across JVMs. Uses Zookeeper to hold the lock. All processes in all JVMs that use the same lock path will achieve an inter-process critical section. Further, this mutex is "fair" - each user will get the mutex in the order requested (from ZK's point of view)

        this.client = client;
        this.listener = new WrappedListener(this, listener);

        this.executorService = executorService;

            protected byte[] getLockNodeBytes()
            {
                return (id.length() > 0) ? getIdBytes(id) : null;
