大家来看看这个线程的写法是不是有问题！！

Question

private void AcceptConnections()
    {
        while (true)
        {
            // Accept a connection
            Socket socket = _serverSocket.Accept();
            ConnectionInfo connection = new ConnectionInfo();
            connection.Socket = socket;            // Create the thread for the receives.
            connection.Thread = new Thread(ProcessConnection);
            connection.Thread.IsBackground = true;
            connection.Thread.Start(connection);            // Store the socket
            lock (_connections) _connections.Add(connection);
        }
    }    private void ProcessConnection(object state)
    {
        ConnectionInfo connection = (ConnectionInfo)state;
        byte[] buffer = new byte[255];
        try
        {
            while (true)
            {
                int bytesRead = connection.Socket.Receive(buffer);
                if (bytesRead > 0)
                {
                    lock (_connections)
                    {
                        foreach (ConnectionInfo conn in _connections)
                        {
                            if (conn != connection) 
                            {
                                conn.Socket.Send(
                                    buffer, bytesRead, SocketFlags.None);
                            }
                        }
                    }
                }
                else if (bytesRead == 0) return;
            }
        }
在AcceptConnections()里产生大量的Thread怎么释放？？
