The eagle-eyed will spot that basic.reject{requeue=false} does exactly 
the same as basic.ack. The difference is one of declared intent. But 
that difference may become more significant, e.g. we have a feature on 
our todo list to add the ability to for the broker to re-publish 
rejected messages to a configurable "dead-letter" exchange.
