Yes. I wrote BlockingConsumer but meant QueueingConsumer.

Yes, I was aware of that. But hence Executor implementations use
concurrent queues (and QueueingConsumer does also) I was thinking
about using a single channel and some Executor instance. As far as I
understand there is no real benefit in using N channels for N workers
- the channel model seems to be there to multiplex N AMQP connections
into one logical i.e. TCP/IP connection.

Best regards,
