Well, I think the end user can track the progress, but we don't currently have
a systematic way of catching "stuck" jobs. But that's a failure scenario that
should hopefully be rarer than consumer acknowledgement timeouts. We'll get
there. I'm curious to hear what Michael and Luke from RabbitMQ advise...

That does sound interesting. Could you explain that one more?
