MessageQueue.BeginPeek and ThreadPool

I've set a up asynchronous callback to be fired when a message arrives at a
certain queue - from my understanding how do I actually remove it if I want
to actually process it?

What happens if two applications are peeking the same queue? do they both
see the same message?

In the good'old days I used to limit the amount of threads running i.e
processing the messages received from the queue by using a semaphore - I saw
a message posted way back that said that Semaphore would be in beta2 anybody
know what happened? What I'm going to do now is determine how many free
threads are available in the pool and if there are less than 5 don't bother
processing the message?


Regards
Robert.
