FYI Igor's latest documents at:
http://nginx.org/en/docs/http/request_processing.html suggest the
following configuration:

server {
    listen       80  default_server;
    server_name  _;
    return       444;
}

You will note that now we use default_server, the server_name _, and
no need for a location to hold the return code.
