Comment (by nickm):

 {{{
 +    if (family != AF_UNSPEC && i->ifa_addr->sa_family != family)
        continue;
 }}}

 This means that in addition to AF_INET and AF_INET6 addresses, AF_UNSPEC
 will get you anything else that tor_addr_from_sockaddr can decode,
 including (for now) AF_UNIX addresses.  How do we feel there?  I'm worried
 that we might have some code that uses these addresses that assumes (for
 example) that everything is IPv6 or otherwise IPv4.
