I'd go so far as to say that anywhere where you want a non-"volatile" atomic_read, either your code is buggy, or else an int would work just as well.
Even, the only way to implement a "non-volatile" atomic_read() is essentially as a plain int (you can do some tricks so you cannot assign to the result and stuff like that, but that's not the issue here). So if that would be the behaviour we wanted, just get rid of that whole atomic_read() thing, so no one can misuse it anymore.
