Exactly!

This is all in an effort to bring down compile times, avoiding including anything from the standard because you can never know if including <atomic> is bringing 10K lines of code in your header.

I will probably provide an optional USE_STANDARD_HEADERS flag someday to allow including a few standard things, including atomics, to avoid doing things wrong on compilerS that are not tested enough (as I clearly can't test every compiler).
