	maybe the above commit changed the goal slightly.
	the goal of multicast kludge table (which i ported from
	sys/netinet6/in6.c) was to keep multicast group information ONLY,
	when all the interface address is gone.  it was not my intention
	to avoid the removal of the last IPv4 interface address.
	could you tell me why is the change?

	this refers to in_purgemkludge(), correct?  i experimented this
	with IPv6 case and IPv4 case, and don't understand why we have
	dangling pointer.   i assumed that in_purgemkludge() is called
	only after we flushed all interface addresses.
