So... without recapitulating the flamage on this that occurs regularly in
r.g.m.*, how do you handle things like the "Dragon's Dinner" scenario,
where the player thinks she has closed the door behind her, but then is
surprised when she is fried by the dragon anyway (who, in this race
condition, saw the door as "open" and went through)? In a truly lockless
system, aren't race conditions inevitable?
