use plain channel?

//reapChildren calls Wait4 whenever SIGCHLD is received
func reapChildren() {
	sigs := make(chan os.Signal, 1)
	signal.Notify(sigs, syscall.SIGCHLD)
	for {
		<-sigs:   // <--- use plain channel?
		for {
			var wstatus syscall.WaitStatus
			_, err := syscall.Wait4(-1, &wstatus, 0, nil)
			for err == syscall.EINTR {
				_, err = syscall.Wait4(-1, &wstatus, 0, nil)
			}
			if err == nil || err == syscall.ECHILD {
				break
			}
		}
	}

I want to use plan mode on coding

I'm confused by what you're asking. What is "plan mode on coding"?

The code is inspired by other golang reaper implementations, such as
https://github.com/ramr/go-reaper/blob/master/reaper.go

because k3s is my project's upstream. came across an report from deepsource.io. So I want to know how.

My question is whether this code can be optimized
