Maybe.  As I said, I'm not familiar enough with that code to really know
what are the consequences, I just mentioned a few potential problems
(without even knowing whether they're real).

So unless someone more knowledgeable can confirm that the patch is
"obviously safe" I don't want to see it in the emacs-24 branch.
