I don't know.  We then would have two interfaces doing about the same
thing and a flag indicating whether the new or old one was used to
create the link so that exclusive close can decide to remove it or
not, which seems a bit complicated.  Let's see whether Mike can remove
the weirdness from dm side.

Thanks.
