Actually, AMQP (and RabbitMQ) *does* support this. When a consumer does 
a 'basic.consume' with the 'exclusive' flag set to true, then any other 
consumer attempting to consume from the same queue will get an error 
until the exclusive consumer has disappeared (through basic.cancel, 
channel/connection closure, client/network failure, etc).
