What I've seen is that a cloning route to the link-local-multicast
for the address that's being detached isn't going away, and that
would be what's holding onto the reference, I'm guessing.
If you build your kernel with IFAREF_DEBUG, you'll get lots of messages
on your console for where references are added and deleted, and when
the ifaddr struct is actually freed.
