I don't know enough about the "GC driven unload" you mentioned, but if
that is not bulletproof enough, we could add a kill-emacs hook to take
care of this. And if push comes to shove, we could use a Windows API
that causes a file to be deleted when the last handle on it is closed,
but that would add complexity, so I think we should try easier ways
first.

But that's unportable, and won't work on Windows, for the same reasons
as the issue we are discussing here. Or am I missing something?
