Here be dragons. If the game/etc program aborts or crashes or exits, leaving
the interrupt vector entry pointing to where the program was, the interrupt
will after that always crash, until you reboot. What is needed is an easy way
for a user to write a TSR and then activate and deactivate it at will.
