Aiohttp recomended deploy Gunicorn + Nginx

I'll need some details on this:

• What kind of socket connection is the transport working with? I.e. this exception can only be triggered if the socket is not AF_INET or AF_INET6.
• Can you provide the source code that exhibits the problem?
• Were you able to reproduce this on other OSes?

1. Yes, the problem is when connect via unix socket.
2. Test add. Main config Nginx - default.
3. Sorry, no other OS.

Seems that somehow gunicorn or aiohttp bind UNIX address using a TCP server (loop.create_server, instead of loop.create_unix_server).

@asvetlov Do you have any idea what's going on?

Ah, I got it: python/asyncio#453

This should be fixed in aiohttp 1.1.2 and uvloop 0.6.1. Feel free to reopen if anything.
