I love how simple this is- Barely 100 lines or C++ (ignoring comments). That's one thing that makes me prefer X11 over Wayland.

The code is a little weird. There is no XLib event loop. It calls sleep(100) in a loop until it hits SIGINT. That will have high cpu usage for no reason.

This is a sleep which allows the kernel scheduler to move to a new process and not a busy-wait so it will have very very low processor usage.
