Deadlock with no coroutines started when calling goccm.WaitAllDone()

[StephanieSunshine]

Why is this causing a deadlock? I would assume that this would pass cleanly because no coroutines were started/nothing to wait for. I don't know what it would be deadlocking on. Is there something I'm missing?

func main() {
	threads := goccm.New(16)	
	threads.WaitAllDone()
	fmt.Println("Hello, playground")
}

Error from Go Playground:

fatal error: all goroutines are asleep - deadlock!

I found a work around, I'm not sure if it's the proper way to be doing this, but if you call goccm.RunningCount() and it happens to be non zero, then goccm.WaitAllDone() doesn't seem to deadlock.
