Timeout for stopping an infinite loop

[BillWagner]

Describe the bug

See dotnet/docs#18801

At one time, we had a timeout configured so that if a user in a tutorial makes a mistake and creates an infinite loop, it would time out. That seems to be gone.

That's a very useful feature for beginners.
