It's evil because `with-output-to-temp-buffer' may pop up a new frame
while `save-window-excursion' gives you the false impression that it can
cope with that situation.

It should be unrelated.

`save-window-excursion' and not `save-excursion', I presume.

I still don't know whether you are sure that Drew runs some code within
`window-configuration-change-hook'.
