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.

It will not, even adding just a 1ms sleep in a loop will drop CPU usage to barely noticeable levels, 10 wakes a second is barely anything for any CPU from the past 3 decades.

This is what the pause(2) syscall was made for, waiting for a signal forever.
