> Atomics in signal handlers - N2547 - its listed as missing here (at msdn), but listed as done here at vc blog
That was me being cautious, see http://blogs.msdn.com/b/vcblog/archive/2015/04/29/c-11-14-17... - "I previously listed "Atomics in signal handlers" as No, because despite maintaining <atomic>'s implementation, I didn't know anything about signal handlers. James McNellis, our CRT maintainer, looked into this and determined that it has always worked, going back to our original implementation of <atomic> in 2012."
