>
> ZookeeperDistributedLock may hold the lock and not release it when the unlock 
> operation was interrupted.
> Because the unlock operation contains two steps: 
> 1. peekLock: get the owner of the lock
> 2. purgeLock: purge the lock if the owner of the lock is the current client.
> If the peekLock step is interrupted, the purgeLock step won't be executed. 
> Thus the lock won't be released.
> Meanwhile, the lock operation should also consider the interrupt cases.
