That *may* not be such a good idea because the interaction within a
channel is conversational. You may run into trouble when executing
synchronous calls within the channel (queue declaration and binding
for example).

Channels are multiplexed into a single AMQP connection which is
invariably but not necessarily tied to a single TCP connection.
Channels were actually designed to do this kind of thing :-)
