Hello Peter

Replying to a message of Peter Fitzsimmons to Alan Clifford:

Thanks for the reply.  I seem to be getting an understanding of what's
going on.  I was surprised that OS/2 didn't pre-empt the thread.

With new stuff like this, I like to try things out a bit at a time before
attempting to use them for real.  I tried making the threads foreground
priority - this devastated the response of a text editor running at the
same time.
