> queueQuery is currently holding a lock on the queue to get a strict message count on the queue.
> In case of high performance scenarios mixed with an anti-pattern on the client with calling queueQuery constantly this will incur on low performance.
> this is an anti-pattern and not much we can do, but we don't need to hold a lock just for that query.
