[rabbitmq-discuss] Published message not queued after publish-ok received when connection quickly closed

the code is similar to the one I originally posted

    @queue1.subscribe(:ack => true) do |metadata, data|
      @channel.default_exchange.publish(data, \
        :routing_key => @deliver_to, \
        :persistent => true, \
        :nowait => false)
      puts '.'
      @channel.tx_commit # <-- if not present, there is always one unacked
msg in @queue1

it wasn't hanging, but because of the tx_select, the ack didn't happen until
the next time the consume callback was run, which I fixed by introducing
another tx_commit right after the ack. mind you, with one tx_commit right
after metadata.ack I lost messages.
