What if it failed to Close the socket at the beginning then try to Dispose it again? There is no socket.IsDisposing or socket.Disposed to use.

    public void Close()
    {
      if (Socket.s_LoggingEnabled)
        Logging.Enter(Logging.Sockets, (object) this, "Close", (string) null);
      this.Dispose();
      if (!Socket.s_LoggingEnabled)
        return;
      Logging.Exit(Logging.Sockets, (object) this, "Close", (string) null);
    }

This is what the call looks like internally. All is fine with my pull request.
