[rabbitmq-discuss] High cpu usage for Java RabbitMQ client?

I have implemented the Basic.Qos to limit to 10 the prefetch size. All
of my messages are marked as immediate, so that if a client gets backed
up, my understanding is that the message will be silently dropped for
that queue. This seems to be the case, if I add a queue but do not
consume messages, the broker does not continually consume extra memory.
The broker is from the mercurial repository, the last status that hg
info reports is this:

summary: Merge with upstream default
The java client is from the same pull, on the same day.
All of these are running on Linux, generally Ubuntu (my development box)
but I setup the broker to run on Debian 5.0. JVM version build
I can reduce the code to a simple example. The outline is basically I
have a few runnable's that open a channel, perform QoS, open an
exchange, and bind a queue. They then sit in a loop using
.nextDelivery() from the QueueingConsumer.

I will follow up with some equivalent code samples later, I'm just
trying to narrow down where the problem is, and prefer to not waste too
much time from other people if no one has seen this issue but me.
