Nope, I tried that.  It turns out there's an annoying edge case that
makes it not work in this case (from line 496):

         * check for special cases.  (1) numeric servname is disallowed if
         * socktype/protocol are left unspecified. (2) servname is disallowed
         * for raw and other inet{,6} sockets. 

The real problem is that we should either not use getaddrinfo to make
sockaddrs or we should do it on demand when we actually have what we
need (i.e. a service name and protocol).
