Mono 2.2 bugs

Socket ObjectDisposedException

Test case:

using System;
using System.Net;

namespace HttpListenerTest {
    class Listener {
        static void Main(string[] args) {
            HttpListener listener = new HttpListener();
            listener.IgnoreWriteExceptions = true;
            listener.Prefixes.Add("http://*:8000/");
            listener.Start();
            Console.WriteLine("listening...");
            listener.BeginGetContext(RequestHandler, listener);
            while(true) {
                System.Threading.Thread.Sleep(250);
            }
        }

        static void RequestHandler(IAsyncResult ar) {
            HttpListenerContext httpContext = null;
            try {
                HttpListener listener = (HttpListener)ar.AsyncState;
                httpContext = listener.EndGetContext(ar);

                // start listening for next request
                listener.BeginGetContext(RequestHandler, listener);

                // invoke response handler
                ResponseHandler(httpContext);
            } catch(Exception e) {
                Console.WriteLine(e.ToString());
                if(httpContext != null)
                    httpContext.Response.Close();
            }
        }

        static void ResponseHandler(HttpListenerContext httpContext) {
            byte[] buffer = System.Text.Encoding.ASCII.GetBytes("hello world");
            httpContext.Response.OutputStream.Write(buffer, 0, buffer.Length);
            httpContext.Response.Close();
        }
    }
}
