        getaddrinfo was designed to be extensible as was struct
        addrinfo.  Part of the problem with TTL is not data sources
        used by getaddrinfo have TTL information.  Additionally for
        many uses you want to reconnect to the same server rather
        than the same name.  Note there is nothing to prevent a
        getaddrinfo implementation maintaining its own cache though
        if I was implementing such a cache I would have a flag to
        to force a refresh.
