def _cleanupNodeRequestLocks(self):
'''
Remove request locks where the request no longer exists.
Because the node request locks are not direct children of the request
znode, we need to remove the locks separately after the request has
been processed. Only remove them after LOCK_CLEANUP seconds have
passed. This helps reduce chances of the scenario where a request could
go away _while_ a lock is currently held for processing and the cleanup
thread attempts to delete it. The delay should reduce the chance that
we delete a currently held lock.
