Does py-amqp do anything with flow control messages?

[endophage]

It seems like py-amqp only sets the Channel.active flag when receiving flow control messages. Is this accurate?

Does that then mean it's the job of services important and using py-amqp to check this Channel.active flag and do something sensible? It seems like Celery/Kombu don't pay attention to the flag and simply try to keep sending messages when the channel has gone into flow control.
