Do the modules import stuff that's staying imported? That could
majorly affect performance. What about .pyc files?

I don't know if you can truly reset the interpreter. Snapshotting
sys.modules and reinstating it afterwards would help, but there are
other concerns too. I would personally just restart the interpreter
each time, frankly; it's the easiest way to be sure.
