Would you mind changing it to `ReadNoFence`? I think it's better as it is a relaxed atomic operation, and we only need the acquire semantic on the interlocked exchange. I think it's the last nitpick I have.
FWIW on x86 it doesn't really matter, since reads are always atomic, and compiler can't re-arrange them due to the other atomics as you mentioned. But `ReadNoFence` is indeed correct for other architectures though.
