I think getaddrinfo_a would not give you much, as you can't
select()/poll()/kqueue() on a sigevent and there's no aio_connect AFAIK and.
This means you would still need two separate threads as you use two different
kinds of async I/O (fd + select()/poll()/kqueue() vs sigevent). Async
connecting is pretty broken in POSIX, IMHO.
The only solution would be to write a new async resolver that can use an
existing select()/poll()/kqueue() call. Because if you need to have two
select()/poll()/kqueue() calls at the same time, you have earned nothing -
again.
