Are they both output values? I believe so, and if that's the case
then they should both go in result_pool.

(This is actually a bit tricky, since the file isn't strictly an
output parameter, but it is instead a tangible side-effect of the
function, which we want to persist for some amount of time. Stuff
allocated in scratch_pool isn't guaranteed to exist beyond the scope
of the function.)
