Comment:
libwnck adds a NET_WM_STATE_FULLSCREEN status apps can use to prevent
the screensaver from lockong while in fullscreen mode (gnome-screensaver
respects this setting), i think something like
NET_WM_STATE_LOCK_OVERRIDE with the same functionallity should be added
to libwnck to make it possible for the screensaver to determine that an
app is trying to prevent the locking (indeed ekiga could abuse the
fullscreen state as a workaround)
