- I looked in my copy of "The Design of OS/2" for the answers to the
- aforementioned questions and learned a number of things, including that
- the kernel is indeed non-preemptible but can be interrupted. Also, that
- process can have their priority boosted under different conditions.
- Another question we had concerning real-time issues was answered:
- Time-critical tasks have a maximum reschedule time of 6 ms after they're
- ready to run. This was also important to us.
-
- Peter Forsberg posted a reply reiterating the same information. Thank you
- Peter!
-
- It's funny, the two inclinations I had regarding the two issues were exactly
- opposite to reality! Just goes to show that I should stick to what I
- know and look stuff up before I ask!
-
- Thanks for all consideration!

- P.S. Based on the discussion we had on Wednesday here, OS/2 got some pretty
- good grades on our criteria and is still in the running! Hurrah!
