That'd strike me as a bug in the network service in question more
than in our chroot(). Unless you're suggesting that chroot()ed
processes should not be allowed to use lo0 or connect to any local
device's registered IP addresses (this gets really fun with
multi-homed hosts).

While we're at it, shall chroot() disallow compromised services
running within a jail from attacking other hosts? Seems within the
same scope to me. (That is, I just don't think it's doable.)
