Sure, I could do dirty region tracking.  Only problem is that if anyone
accesses the framebuffer directly, it'll get out of sync, because there is
no way to keep tabs on what people do to the emulated framebuffer directly. 
Only way to do reliable dirty region tracking is if you don't emulate a
framebuffer.  I'm just going to stop trying to emulate a framebuffer, and I
can actually just let ncurses' existing dirty region tracking code do its
thing for the present.

Well, IIRC Andy wants that DOS port ... we need to figure out SOMETHING...

It might be an interesting excercise cobbling together a dynamic linker for
DJGPP -- I expect it's doable.
