	A)  The 1.2 OpenScreen will lose a small amount of chip memory
	    if the open fails.  Sorry, you'll have to live with it for now.
	B)  If vd0: is running low on memory, it will use chip ram.  Chip
	    ram is MUCH more likely to get hit in a warm boot than fast
	    memory.  Solution: don't set a vd0: for more than 1.5Meg on
	    an amiga with 2 meg of FAST memory.

	Getting back anything from a dead process is risky at best.  If you
want to try, check out GOMF.
