[Mono-dev] NancyFX self hosting (HttpListener) locking up on linux

[Nikita Tsukanov]

https://github.com/kekekeks/scgi-sharp - here is my SCGI server with host
for NancyFx. If you run Sandbox.exe with --echo-server it will not use
nancy infrastructure and will respond directly. It locks up after several
thousands of requests under jmeter.

Simple nginx configuration:

location /
{
   include /etc/nginx/scgi_params;
   scgi_pass 127.0.0.1:10081;
}

Now I'm looking for alternative socket library to use it as a replacement
for System.Net.Sockets.
