 I also find the existing behaviour useful with VPN links, which go down
 and come back up with the same IP address when I move my laptop from one
 location to another.
 
 It might be nice if "ifconfig ${interface} [down|destroy]" or "ifconfig
 ${interface} ${family} ${address} delete" had an extra flag to mean
 "also invalidate any sockets bound to this address, or to any address on
 this interface".
