I did end going this route. Instead of the `gdk_keymap` functions, I now use
`XkbGetNamedIndicator`. It works on both GTK2 and GTK3 (unsurprisingly, since
it isn't using GTK / GDK at all), and correctly reports the state of the keys
even if the lock state is toggled when the program is not running or does not
have focus.
