---------------------------------------
bq. So I think the locks are actually released, they just leave behind some
benign znodes that only take up space.
Yes, Looked into more details, long staying lock doesn't have any
getParticipantNodes. They are just not cleaned up.
> ZK locks are not released after server shutdown

> ZK locks are not released after server shutdown.
> Lock count before and after shutdown remain same.
> One of the reason is that, locks are not ephemeral. It should be ephemeral
> lock, so that if nodes goes down, locks will be automatically released
