In that case, read
/OSAtomic/> and tell me if it answers your questions.

As I mention elsewhere in the thread, Apple's documentation is flawed on this
matter: they document kernel calls (e.g., OSIncrementAtomic) better than the
userland calls (e.g., IncrementAtomic), but this issue will be addressed in the
future, and it's safe to assume that the behavior of the userland call (which I
believe we should use) is the same as the documented behavior of its kernel
counterpart (whose documentation I referred you to above).
