OK. The spacemacs initialisation code uses this variable (along with
ns-initialized and x-initialized) to ensure that certain actions (e.c.
find-font) are only run after the display is initialized. It's only
w32-initialized for which this approach doesn't work. Is there a
better way of testing for this situation that should be used?
