Admittedly I don't really see gcc ever reloading the value in the middle of the loop, so the ACCESS_ONCE() protects us from a fairly theoretical issue. But better safe than sorry. Also, this consolidates the common parts of the word-at-a-time and bytewise logic, which includes checking the length. We'll be changing that later.
