> AMQP 0-8..0-91 has a concept of default queue. This is the default queue to which operations such as basic.consume apply if the client chooses not to pass a queue argument within the command. The default queue is defined as the queue that is most recently declared, passively or otherwise by a queue.declare command.
> There is the potential for a leak in the current implementation of AMQChannel's default queue implementation. It retains a reference the queue that is the default even if the queue is deleted. It would be safer if the default queue reference is cleared if the queue is deleted (either explicitly by a queue.delete or the side effect of the cancelling of a consumer).
