# unused before it is automatically deleted. Unused means the queue has no
# consumers, the queue has not been redeclared, the `queue.get` has not been
# invoked for a duration of at least the expiration period. In our case this
# period is equal to the request timeout, once request is expired - queue is
# no longer needed.
