The paragraph on http://www.rabbitmq.com/consumer-prefetch.html
> Example - multiple consumers sharing the limit
> The AMQP specification does not explain what happens if you invoke basic.qos multiple times with different global values. RabbitMQ interprets this as meaning that the two prefetch limits should be enforced independently of each other; consumers will only receive new messages when both limits on unacknowledged messages are met.
Has a curious last phrase (underscored). I think the phrase should be something like: 
consumers will only receive new messages when neither limit on unacknowledged messages are reached.
(modulo the meaning of limits … are met.) 

(Perhaps it should be breached instead of reached.)
