I think I found the best solution to my problem. I made a custom class
derived from Queue, and did override Queue.Enqueue to raise an event
whenever it is used.

Now when one thread puts something in the Queue, it automatically raises
the event, and the event handler calls ThreadNotify.WakeupMain. This way
my back end utilities just communicate via the queue and know nothing
about ThreadNotify, and voila', the uggliness is gone. Also, no need to
poll the queue for new messages.

I know the negative side of using threads, but I prefer them because
they are a more natural way to express oneself when programming. I'm a
cabeza-dura, I know! :) but this is a small project, so I can afford
using them.

Thank you for the help Miguel!

    I am pretty sure that you should be able to poll the Process output.  If
    we do not have a helper routine today to simplify this, we should add
    it.
