如果底层的线程终止了，它会被重新创建。

If the underlying thread dies, it gets re-created.

当线程终止时，操作系统将清理所有分配给线程的资源，其中也包括了关闭任何线程已经打开的会话。

When a thread terminates, the operating system cleans up all resources still allocated to the thread; this includes closing any sessions which it had open.

注意：bot只在启用时调用线程(记住，每个插件都是一个线程)；在线程终止之后，只有在重新调用bot时才会重启线程。

NOTE: the bot invokes threads (remember that each plug-in is a thread) only when it is started; after a thread terminates it is not restarted until the bot is invoked again.
