ConcurrentQueue alternative: https://github.com/cameron314/concurrentqueue
ReaderWriterLockSlim alternative: https://en.cppreference.com/w/cpp/thread/shared_mutex
Task alternative: https://en.cppreference.com/w/cpp/thread/async
new Thread(...) and Thread.Start alternative: https://en.cppreference.com/w/cpp/thread/thread
Thread.Sleep alternative: https://en.cppreference.com/w/cpp/thread/yield or https://en.cppreference.com/w/cpp/thread/sleep_for

Looks like we cannot support InvokeWithExtendedMaxStackSize unless we decide to depend on boost (https://stackoverflow.com/questions/13871763/how-to-set-the-stacksize-with-c11-stdthread)

Instead of ConceuurentQueue and all other concurrent containers: https://habr.com/ru/post/328348/
[maybe later] Instead of std::shared_mutex: more fast https://habr.com/ru/post/328362/
Instead of std::thread use more safe std::jthread

Also, can use https://en.cppreference.com/w/cpp/thread/packaged_task
