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 disallow=
ed
* for raw and other inet{,6} sockets.=20
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).
