当浏览器关闭时，chrome_crashpad_handler和Chromium Helper两个进程没有被关闭。

[DC3x6]

Rod Version: v0.114.5

在多协程的情况下，每个协程开始时初始化一个浏览器，浏览器关闭时，chrome_crashpad_handler和Chromium Helper两个进程没有被关闭，导致内存占满。

func main() {
 var swg = sizedwaitgroup.New(10)
 for i := 0; i < 100; i++ {
 	swg.Add()
 	go func(num int) {
 		defer swg.Done()
 		println(num)
 		browser := testrod.NBrowser()
 		defer browser.MustClose()
 		page := browser.Timeout(20 * time.Second).MustPage()
 		navigation := page.MustWaitNavigation()
 		page.MustNavigate("https://www.google.com/")
 		navigation()
 		time.Sleep(5 * time.Second)
 	}(i)
 }
 swg.Wait()

}

如果 leakless 都不行，那么 chrome 就非常像病毒了。你只能自己处理他的进程了，这是拿到 stdlib 的 cmd 对象的例子：

rod/lib/launcher/example_test.go

Lines 26 to 46 in f8e5736

	func Example_custom_launch() {
	// get the browser executable path
	path := launcher.NewBrowser().MustGet()
	// use the FormatArgs to construct args, this line is optional, you can construct the args manually
	args := launcher.New().FormatArgs()
	var cmd *exec.Cmd
	if true { // decide whether to use leakless or not
	cmd = leakless.New().Command(path, args...)
	} else {
	cmd = exec.Command(path, args...)
	}
	parser := launcher.NewURLParser()
	cmd.Stderr = parser
	utils.E(cmd.Start())
	u := launcher.MustResolveURL(<-parser.URL)
	rod.New().ControlURL(u).MustConnect()
	}

你使用 exec 库的话就和 rod 无关了，这部分实在难以调试和复现。
