Review Comment:
We don't need to test for theoretical situations such as symlinks when we
dont use them in lucene? So I would go with the fastest/simplest route, that
solves our needs.
Its not a generic windows filesystem simulator, just good enough for our
needs, to prevent deleting open files and test the logic surrounding that.
