Test on on rs780 and it seems to work properly, but i haven't really
stress test it beside few games. I see no perf or CPU use improvement
but it could very well be hidden by others cost.
Note that we can't really have concurrent cs due to the way checking
work. Anyway you could add my reviewed by.
