Something like this is indeed needed, but I think you also need to keep
track of which protocol family you ended up using for the socket so that
it can be correctly bound a little later.
I have a feeling all is not 100% right with the code for outgoing IPv6
connections either. I started reworking some of this a couple of months back
but never finished the job.
