basically, BSD code does not really expect to have multiple interface
addresses from the same prefix (for example, 10.1.1.1/24 and
10.1.1.2/24). there are many assumption made about it, including
in_ifinit(). as it is critical requirement for IPv6, KAME team is
trying to cook up better code (it is not yet merged into *BSD).
we will need to bring it back to IPv4 too, it seems.
