The current problem arises from the fact that you're creating sockets
bound to "any address on interface foo", which really means "all
addresses on interface foo", which for an ipv6 socket includes v4
sockets, and for a v4 sockets means that the next similar request for a
v6 socket will choke.
If instead, you're creating sockets bound to "this specific address", then
the original problem disappears (you still need to handle the selection of the
packet parser routine based on the socket type).
