Exclusive queues are owned by the connection that created them. The 
general idea is for that (and *only* that) connection to subscribe 
consumer(s) to the queue. Exclusive queues are deleted when the 
connection goes away.

May I ask why you declare the queue as exclusive? Wouldn't a 
non-exclusive queue fit your use case better?
