> Found this when implementing the POC of HDFS-9924.
> The problem is that channel.writeAndFlush will find the first outbound
> handler before scheduling the actual write task into event loop, so it is
> possible that when we actually execute the write task, the first outbound
> handler has already been changed but the task still refers to the old handler
> which has already been removed.
