+//when it should show screensaver (and maybe lock the session),
+//it starts kdesktop_lock, who does all the locking and who
+//actually starts the screensaver
+
+//It's done this way to prevent screen unlocking when kdesktop
+//crashes (e.g. because it's set to multiple wallpapers and
+//some image will be corrupted).
