влияет на функции now, statement_timestamp - они будут брать кешированное значение с момента инициализации comp graph.
clock_timestamp сейчас всегда возвращает некешированное системное время - это потом надо будет увести в TimeProvider</content>

`#define noexcept throw()` is a questionable idea, since replacing `noexcept` with `throw()` in expressions such as `noexcept(true)` results in spectacular compiler errors. We stopped supporting CUDA 8 (and even CUDA 9) long ago, which means we can just get rid of the problematic define.</content>

For example, https://github.com/google/sanitizers/issues/1352 - tsan is not working well with std::atomic_thread_fence

Minimal reproducible example (and one that bothers most in every fiber-aware service):

```
auto threadPool = NYT::New&lt;NYT::NConcurrency::TThreadPool&gt;(2, "thread");
    
TVector&lt;NYT::TFuture&lt;void&gt;&gt; futures;

for (size_t i = 0; i &lt; 100000; ++i) {
    futures.emplace_back(BIND([]() {
        
    }).AsyncVia(threadPool-&gt;GetInvoker()).Run());
}

for (auto&amp; future : futures) {
    future.Get().ThrowOnError();
}
