When I follow this recipe on my machine, I see no call to
run_window_configuration_change_hook, because adjust_frame_size
returns before that, having discovered (around line 500) that the new
and the old dimensions are identical, and therefore no resize is
needed.

Can you see why this is not so in your case?  Perhaps the calculations
of frame dimensions in the case of Lucid are to blame?

Also, I think linum-update-window should do nothing if 'linum' is not
a valid face on the selected frame, because functions in
window-configuration-change-hook can be called in many situations on
which linum has no control.
