The main concern on the mailing list was that some of the implementation was not using memory barriers/fences, which may be dangerous in some cases. I made the first attempt to make much of the atomic functionality use a sequentially- consistent ordering by using memory barriers. The performance impact seems to be relatively small but we will have to keep an eye on it. I also made some changes to the implementation that will hopefully avoid falling back to critical sections on Windows XP. Change-Id: Ib05f411f905cfe9a89bb8bc82ca103d3c1eb8002
