With that approach the number of consumers must be exactly the same as
the number of queues; if you have fewer then some messages won't get
consumed, and if you have more then some consumers won't process any
Furthermore, you cannot add/remove queues since that will cause some
subsequent messages to get routed to different queues than prior to the
queue addition/removal. They will then be picked up by different consumers.
