> AMQ-850 introduced the ability to set the message prefetch size to 0.
> This means that no messages are prefetched and every receive() call goes all
> the way to the broker to get the next message.
> It was only a valid option for synchronous message receivers.
> In CMS it does not appear to work. Instead, a client set to use this simply
> receives no messages, and the messages remain on the queue.
> Without this patch, it is possible for a slow consumer to hide an important
> message from other consumers because it has prefetched it.
