> {{LockManager}} has a possible deadlock.
> # Number of locks is limited by using a {{GenericObjectPool}}. If N locks
> are already acquired, new requestors need to wait. This wait in
> {{getLockForLocking}} happens in a callback executed from
> {{ConcurrentHashMap#compute}} while holding a lock on a map entry.
> # While releasing a lock, {{decrementActiveLockCount}} implicitly requires a
> lock on an entry in {{ConcurrentHashMap}}.
