Preventing these entries from the lo= cal=20 translation table has been implemented only recently. We can potentially do= =20 the same for global addresses as well, it just hasn't been done so far ... = at=20 least I don't see a reason prevening us from that. It is probably added by= =20 "speedy join" in the first place.
