| 调用`thread.waitForAll({t})`在功能上与调用`t:join()`一致。在进程结束时会对其子线程调用`thread.waitForAll`（若有）。子线程也通过同样的机制阻塞其父进程。 | 调用`thread.waitForAll({t})`在功能上与调用`t:join()`一致。在进程结束时会对其子线程调用`thread.waitForAll`（若有）。子线程也通过同样的机制阻塞其父进程。 | ||

The exception message is not printed to stdout nor stderr (see `t:resume()`) for details. | + | 此样例演示了线程抛出异常时会发生什么。线程在抛出未捕获的异常时会停止执行并进入“死亡”状态。报错信息将不会输出到stdout或stderr（详见`t:resume()`）。 |
