Call on release allows the user to pass a function to be called at destruction of this instance.
One goal was to provide a thread exit cleanup facility, setting a 'is_running' flag to false when the thread exists normally or abnormally.
jau::relaxed_atomic_bool is_running = true; void some_thread_func() { thread_local jau::call_on_release thread_cleanup([&]() { is_running = false; }); ... do some work here, which might get cancelled .. thread_cleanup.set_released(); // mark orderly release }
