Otherwise such a transfer would require more coordination - the original owner would first need to unbind, then signal the completion thereof to the new owner.
Yes, like today's handling of xenstored live update. It is the natural way to do that, as that coordination needs to be happening anyway, as I've outlined in my response to your remark on patch 2. Juergen
