RabbitMQ doesn't impose any limit on channels. Theoretically you may
create as many channels as you have free erlang-process-ids. Which
is usually about 32k.

But in practice RabbitMQ shouldn't be using too many channels.
If you're using more than a dozen of channels for a consumer, you're
probably doing something wrong.

You may run multiple 'basic.consumes' on one channel. But when you
share a channel between threads remember to make sure the access
is synchronized.
