Doing this means that the server consumer can iterate over the queue without a comod exception being thrown.

I'll add a new flag to specify what kind a consumer is, i.e. a browser or not. If a Consumer is a browser the it will not add itself to the queue to receive messages, instead it will iterate over the whole queue sending messages until there are no more. How does this work with flow control? What if the consumer buffer is full before it has iterated the entire queue?
