频道未检测到SIGCONT

I'm trying to replicate a shell environment. The following code runs within os.StartProcess and p.Wait(). It is able to receive C-z (SIGTSTP) and C-c (SIGINT) but not when I send SIGCONT from another shell with kill -CONT [PID].

sigChild := make(chan os.Signal)
defer close(sigChild)
signal.Notify(sigChild, syscall.SIGTSTP, syscall.SIGINT, syscall.SIGCONT)
defer signal.Stop(sigChild)

sigRcvd := <- sigChild
fmt.Println(sigRcvd)

I'm not sure if I missing something in my code.

It's an known issue in Go. There is an issue for it on GitHub.
