No, I think that's a great idea.  Making `make-network-process' totally
asynchronous would be good for general asynchronousness (that should be
a word), too, since the handshake part is synchronous today, I think.

*looks at documentation*  Oh, right.  There's :nowait, so it would make
sense to only use getaddrinfo_a if we've got a :nowait connection.

I can take a look at implementing this (if nobody else feels inspired
to), but I've got one questions to start with:

Is getaddrinfo_a available on all the platforms we care about?  Or is
there a gnulib module for compatibility or something?
