Err, the basic.cancel is unnecessary: the client and server both tidy up
any state associated with the subscription when they receive the
notification. You should just need the new basic.consume. However, this
behaviour is certainly specific to 2.4.0 clients and broker: prior to
this, if you have reason to suspect the queue had silently gone away,
you'd have to cancel and then reconsume otherwise at the very least,
you'd have a (very very slow) memory leak.
