	 * A single tcp/ip server socket.  When created the server socket will bind

	 * connections.  When connections come in they are pooled by the networking
	 * drivers in the kernel until they are accepted, this means that failure
	 * to keep space in the connection pool will result in connection refusals.
	 *
	 * Although the accept function returns an integral file descriptor, it is
	 * designed to be used with the Socket class.
