If your code is too lazy, you have the whole file + the close
operation hanging around in unevaluated thunks until you print the
result and it all gets processed all at once. Laziness is a double-
edged sword.
Where in my code is this laziness hidden? Is it while recurions with
sum and count?
That would be my guess, although I'd have to examine the Core
(intermediate compilation stage) to be certain. Others here are
better at looking at Haskell code and seeing where the laziness
"leaks" are.
