Maybe we can find some better language -- "not allowed" sounds like a permissions check, and we longjmp out on permission check failures. Perhaps "if the page requires i/o access"? Why are you returning NULL for size 0? Just because the caller hasn't committed to a size and thus we haven't checked watchpoints? r~
