To clarify, "default exchange" is AMQP jargon for the exchange with the
empty-string as its name.

  channel.basic_publish(exchange = "", routing_key = queue_name, ...)

The spec mandates that this exchange route directly to queues named the same as
the routing keys used. Whenever a queue is created, a binding for the queue is
automatically created on the default exchange.
