Oops, indeed.

I thought we had ‘mkdtemp!’ but it’s just in Guix.  :-/

Well we can go that way for now, perhaps with a FIXME comment suggesting
the use of ‘mkdtemp!’ once it’s available.

Also please make sure to include a ChangeLog-style commit log.

Apart from that it LGTM!

I think we should add ‘mkdtemp!’ to libguile in a separate commit; it’s
OK to _add_ procedures during a stable release.

Thanks,
Ludo’.
