Why would it 'fire' more than once, there is no loop?

int main() {
    boost::asio::io_context ioContext;
    auto pooper = Pooper(ioContext);
    while ( true ) {
         pooper.Run();
        ioContext.run();
    }
    std::cerr << "Exited..." << std::endl;
}

Now it will poop till you drop.

Other than that, this appears to be [you don't state what you would like to
achieve] some kind of event-loop, where you suspend till the next frame.
You can suspend the current thread with std::this_thread::sleep_for (
std::chrono::milliseconds ( milliseconds_to_sleep ) ); or
std::this_thread::sleep_until ( some_time_point_in_the_future ); using just
std-lib facilities. Having said that, have a look at SFML (
https://www.sfml-dev.org/), which has all those things, event-loop,
event-polling, mouse, touch, joy-stick, sound, image rendering, window
creation etc.
