Redis Pub / Sub ServiceStack，取消线程

RedisMqServer中的示例显示了如何订阅和取消订阅消息，例如：

using (var subscription = redisClient.CreateSubscription()){    subscription.onUnSubscribe = channel =>         Log.Debug("OnUnSubscribe: " + channel);    subscription.onMessage = (channel, msg) =>    {        if (msg == "STOP")        { Log.Debug("Stop Command Issued"); Log.Debug("Unsubscribing from all Channels..."); subscription.UnSubscribeFromAllChannels(); //Unblocks thread.        }    };    subscription.SubscribeToChannels(QueueNames.TopicIn); //blocks thread}

它使用自定义控制消息来取消阻止后台线程，并取消订阅 OnMessage 处理程序的所有通道的订阅。
