My last professional experience with OS/2 was a few years ago, but from
what I know it's fully preemptive. I'm not sure how a human could tell
if the PM was preemptive or serial, since we're mostly serial, but if
keeping a slideshow running while web browsing and playing a CD requires
preemptive multitasking (does it? I don't know, but i'd think so) then
it is. On the other hand, wouldn't a serail multitasking PM be more
responsive?
