The good exercises are the ones that lead you into making mistakes.
This was a good exercise.
At first, I tried to read by creating a new Scanner(os.Stdin). This was a mistake, since the ReadLine method ends up blocking the main thread. After about an hour of being cleverly wrong and trying to interrupt the user's prompt by writing EOF (0x4) to os.Stdin, I ended up looking at the solution to see how the teacher did it.
Lesson is to treat user input as yet another asynchronous message (yaam).
