Connect to unix domain socket

Nginx (and maybe other load balancer) support connecting to backend through unix domain socket. Which is the fastest interprocess communication method. EventMachine also supports connecting to unix domain sockets... Connect the dots :)

Usable like this (Nginx config file):

upstream  backend  {
    server   unix:/tmp/thin1;
    server   unix:/tmp/thin2;
    server   unix:/tmp/thin3;
}

server {
    location / {
        proxy_pass  http://backend;
    }
}
