Creates a nasty race in the current working directory of Emacs,
actually, unless `make-temp-name' is different under Emacs than XEmacs.

It's not portable, nor is the FFI interface. :)  Seriously, though, even
the almost-latest XEmacs doesn't support `make-temp-file', which means
that I would need to emulate it...

Creating a directory in a world-writable folder wouldn't help. I really
should have done:

(let ((filename (expand-file-name (make-temp-name "silly.vi.user.") "~/")))
  ...

That would ensure that one of two things are true:
1) The rest of the world can't write the area the file is in.
2) The rest of the world can write '.emacs'[1], which means the user is
   losing anyway...
