Comment 2 for bug 1296666

This should be implemented in xdg-screensaver, not in Caffeine. Feel free to file a bug against xdg-utils: https://bugs.freedesktop.org/buglist.cgi?component=xdg-utils&list_id=511294&product=Portland&resolution=---

(Note that Caffeine 2.8 will give you a command you can use in wrapper scripts for applications that you want to suspend screensaving whilst running: this is more efficient and reliable than the old process detection.)
