***** Actually,  I believe I have turned off the no_ack flag and am actively
sending acks when appropriate.:

    BasicConsume = #'basic.consume'{
        ticket = Ticket,
        queue = Qname,
        consumer_tag = Tag,
        no_local = false,
        no_ack = false,     % false -> keep msg in queue until consumer
sends basic.ack ********
        exclusive = true,   % We only want one consumer ever on this queue
        nowait = false      % We want to wait for a response from the server
to this message

However, I must have done something wrong because RMQ continues to send even
if I haven't acked.

As for canceling, that's exactly what I am doing, and that's what's crashing
the channel :)
