Ok, makes sense.

Would replacing the queue currently used for unacked_message_q in
rabbit_channel.erl with a queue that overflows to a tempfile be
sufficient to resolve this? I have a (minimally tested) queue that
does that. I guess the calls to queue:to_list would have to be
replaced with something fold-based or it would defeat the purpose of
the whole thing, but is that basically what needs to be done?
