Yes, it does.

I'd bet you can't.  It's more than likely that QUAKE needs all of its code
and data in memory all the time (or else it won't be able to service all
the hardware interrupts it hooks, like keyboard, mouse, timer...), so it
probably checks the amount of physical memory installed, and will refuse
to run if you don't have enough.

Yes, it's deleted when CWSDPMI exits.
