Curiously, the times reported for "outside" are about 5-8 times as long.

What is the cost of putStrLn relative to performing `stuffToDo` a few hundred times?

I am not sure.... it still takes about 5-8 times longer whether `stuffToDo` recurs a few times, a hunded times, or about a thousand times.

Perhaps I will try and force `stuffToDo` not to leave any partially evaluated thunks behind.... and compare the cost then.
