Since this article predates the Microsoft-IBM split, I figured it was safe to consult my trusty Inside OS/2, by Microsoft’s Gordon Letwin: The scheduler's dispatch algorithm is very straightforward: It executes the highest-priority runnable thread for as long as the thread wants the CPU. When that thread gives…
