The cleanup of dequeued messages is done on the receive path with the Queue's messageLock
held (has to be held).  When multiple consumers with large ack windows are sharing the queue,
a large backlog of messages can build up.  Performance of the consumer can be improved by
rate limiting this queue cleanup.
