Don't get me wrong, I understand that atomic operations require CPU support. My point was that `atomic` allows you to get access to these operations in a more standard way for different platforms (And of course, it will fall back to generic locking in the event you use an unsupported width or operation - but that's arguably better then simply not working at all).
