systemd lid switch behavior is configured with HandleLidSwitch=, HandleLidSwitchExternalPower=, HandleLidSwitchDocked= in /etc/systemd/logind.conf

Any sane compiler will simplify this into

    function cosmicRayDetector() {
      while(true) {
      }
    }

C++ may further ‘simplify’ this into

    function cosmicRayDetector() {
      return
    }
