The getaddrinfo specification and its refinements that make it clear
that this interface is not just there to get the raw address information
out of DNS, but also to perform address sorting based on various
factors, including network topology information. It's not much of a
stretch to include address priority information from DNS as well.
I'm not saying that we should go down this path, I'm just trying to
explain why I didn't want to close the RFE immediately.
