The doc claimed an in-flight failure re-surfaces the messages on a later drain, because the ack is local. That was true when InMemoryReplyInbox was the only inbox, and became false without anyone noticing when the AMQP adapter landed: there the ack is a broker-side basicAck, so a crash while writing the response loses the reply outright. Re-polling cannot recover it, since the broker has already forgotten it. Behaviour is unchanged and the window stays accepted — acking on the next poll instead would double-deliver on every normal drain. The point is that the comment sat exactly where the next implementer would read it and said the opposite of what happens. Closes #12.
