You do not want to be using it by default, because this can leave for example an orphan child, orphaned children processes.

您不希望默认使用它，因为这可能会留下孤儿进程、孤儿进程等。

Like if a process has other small children processes that it started, and you SIGKILL it, all of those will keep running in there, but they won't have a parent, and you can maybe have a really weird behavior going on.

就像如果一个进程有其他它启动的小子进程，并且您对它发出 SIGKILL 信号，那么所有这些进程都会继续在那里运行，但它们不会有父进程，并且您可能会发生非常奇怪的行为。
