I have plan to support persistent connection to proxied and FastCGI servers.

Sorry, it's difficult to me to write in English, so I will be short:
I do not think that AIO support in nginx will add huge perfomance boost

1) You can run 100 worker processes to issue 100 simultaneous disk
    IO operations. You can not do it with lighttpd and other single process
2) There is no AIO sendfile.
