--- Comment #12 from Mkkt Bkkt <valera.mironow at gmail dot com> ---
First of, I was a toxic, sorry.
But you start this first, maybe it's allowed for maintainer, I don't know.

But I still waiting code of benchmarks.

Also I want to see example of usage when we notify atomic, that in
non-deterministic wait state. And we cannot make this optimization outside =
of
libstdc++.

Because honestly I don't understand purpose of this optimization except
benchmarks like

```
atomic<int> x;
while(...) {
  x.notify_one();
}
```=
