Actually, OS/2 is not all that impressive when it comes to running Windows
programs in separate VDMs.  Try this: set Word to run in a separate session,
and then go find the Word icon and double click on it 20 or 30 times.  Watch
OS/2 crawl, if not totally die.  On NT, it actually works.

Furthermore, if you limit yourself to only 10 or 15 copies of Word (!),
when I tried this on a 12 MB machine, NT actually managed to get them all
going without significant swapping.

My speculation is that IBM's separate Windows sessions are a little bit
too separate.  I think NT is taking advantage of copy-on-write to avoid
making the sessions completely separate until something actually needs them
to be completely separate.

Of course, OS/2 is a lot better than Windows non-NT at running a lot of
copies of Word in separate sessions.
