Every "load:" call already runs its own interpreter. I guess the
session is sticking around somewhere in-between.

I've been playing around with hint and the GHC API trying to figure
this one out (with Simon's tips in mind), but haven't found a way to
discard the session, or even on what level that should be done. In
runInterpreter? Or in separate runGhc calls? The best guess I have so
far is using getSession/setSession inside the interpreter call to
restore it to the way it was before, but that seems to have no effect.

Here's what I'm using to test:

Even with setSession, the cache seems to be sticking around -
subsequent loads are faster, and the memory usage doesn't go down.
