I don't think my proposition necessarily prevents this. It just means that
save-window-excursion should re-select the original frame before doing
the set-window-configuration.

Admittedly, I think the above code is mistaken. It kind of reminds me
of the infamous (save-excursion (set-buffer) ...), although in worse
since, like Martin, I despise save-window-excursion.
