Research direction

Start by reading the SourceLoader implementation and reviewing the referenced python/cpython#3963 pull request. Confirm the current behavior around equal mtime seconds and identify the existing interpreter tests that cover bytecode loading; done means SourceLoader no longer uses stale bytecode in that case.
