It looks like Jason Thorpe just described outlines for ways to go about
a MI implementation.

Chris, have you looked at making the top half MI while making the grunt
laborers MD?  It's not an unheard-of premise...

[actually, I'm sure you must have looked at that concept by now, and you've
 probably hit some performance problems; but it's REALLY hard to hit a MI
 solution which doesn't suck performance-wise.]

ddb: greywolf.cow.c: 511: wp =(worm_t *(*)())(*greywolf)->func[OPENCANOFWORMS]\
		((worm_t (*)()) cow_open, (worm_t *) can_of_worms) \
		finally returns (worm_t) {
			    worm_t *worm = 0xc0ffee;
			    int nworms =   4492839200598829548;
			    func =	   0xffe8900c (close());
			    flags =	   0x00028000 (NOWYOUDIDIT|GOODLUCK);
		}
ddb: greywolf.cow.c: 513: wp->func(main_worm) fails with EIO
panic: kernel cannot close large can of worms!
Well, you ran into something and the game is over.
