  Yeah, actually, as happens oh so often, as soon as I posted to this, I 
realized what to do.  I took everything out of the interrupt vector (put 
it in a badly timed, but effective while loop) and let it go.  Since 
interrupts were NOT disabled when this happened, I got a unsupported int 
0x00, and THEN a divide by zero error.  (int 0 is divide by zero.)  But 
now, once in every whole bunch of times when I try to exit, I get an 
unsupported int 0xD.   Oh well.  I'm not going to worry about it unless 
it happens again.  :)
