I can post the URL of the discussion.  It was a very long discussion,
most of it dedicated to Stefan's review of the proposed patch.  That
patch was eventually not admitted, because the author won't sign legal
papers as required by the FSF rules.

I agree, but the problem is that now someone needs to re-implement
that changeset from scratch, without looking too much at the patch
posted back then.  I cannot be that someone, unfortunately.
