Pretty sure that's what's going on here.  When Guile makes server
sockets, it assumes it should listen on a single family/address/port
triple.  Specifically for INADDR_LOOPBACK that's going to be IPv4
127.0.0.1 and not IPv6 at all.  Probably we should use getaddrinfo if
the user supplies a "host", and use that to plumb through a list of
addresses on which to bind (and/or connect).
