 From mythmainwindow.cpp handling a Lirc keycode
 ---
 if (keycode)
         {
             GetMythUI()->ResetScreensaver();
             if (GetMythUI()->GetScreenIsAsleep())
                 return;
 ---
 ResetScreensaver (in screensaver-x11.cpp) invokes

      myth_system("gnome-screensaver-command --poke

 So there is a fork/exec of gnome-screensaver-command on every Lirc key
 press. On a system with little free memory this can several seconds per
 keystroke.

 The strategy should be changed. At very least there should be an option to
 disable screensaver checking.
