从预加载脚本启动工作线程

从预加载脚本（使用 -r 命令行标志加载和运行的脚本）启动工作线程时要小心。 除非显式设置了 execArgv 选项，否则新的工作线程会自动从正在运行的进程继承命令行标志，并将预加载与主线程相同的预加载脚本。 如果预加载脚本无条件地启动工作线程，则每个衍生的线程都会衍生另一个直到应用程序崩溃。

Take care when launching worker threads from preload scripts (scripts loaded and run using the -r command line flag). Unless the execArgv option is explicitly set, new Worker threads automatically inherit the command line flags from the running process and will preload the same preload scripts as the main thread. If the preload script unconditionally launches a worker thread, every thread spawned will spawn another until the application crashes.
