[rabbitmq-discuss] TTL on Consumers in PHP

Michael -

Apologies for asking you to be pedantic, but I'm still a little hazy on how
I would implement my desired behavior.

I actually have the 'quit' functionality embedded in my callback, though I
stripped it out for my example for simplicity. With or without though, when
I run my consumer, my code hits the '$this->channel->wait();' line and
doesn't exit until an external event (new message) enters the queue. My
preference is that a Consumer itself knows when it has sat idle long enough
to terminate itself rather than having an external process monitor it.

Should this be done by subclassing AMQPChannel? Like I said, I'm still a
little hazy.
