> SimpleAMQQueue uses an atomic reference to round robin the subscriptions when attempting
to deliver a mesage to a subscription during enqueue operations. This reference will prevent
the subscription being Garbage Collected when it is closed if the subscription was the last
used and no more messages are enqueued. When unregistering a subscription, this reference
should be updated if it points to the closing subscription.
