AFAIK, finalizers are not guaranteed to be run at all. There are some profound
reasons for this, but I didn't bother to learn them. Anyway, in this case we
could simply register all directories created with withTempDir somewhere (in a
mutable variable), and then *explicitly* remove all registered directories at
exit.
