In the man pages it says EAI_SYSTEM should set errno. Probably makes sense to
set that here...?

That would be a little more complicated, since our internal
getaddrinfo could then need to return two error codes somehow.
I'm not sure we have any more fine-grained information to
store in errno anyway, so I'll leave this is a TODO if thats
OK.
