- Well, you could bite the bullet and peek at the low-memory area where the
- modifier flags are kept (which is obviously what PPostEvent is doing). And
- if your code is very successful and you make a lot of money from it, then
- you'll have the resources to bring out a new, slower version when it breaks
- under a future, faster machine. :-)
