Yeah but it's temporary. You can free it once you're done sorting. It won't
interfere with anything... it'll just come and go in the blink of an eye...

Still, you must read the whole directory and sort it before you can
cache 200 of the files in it. To do that, you need a temporary
storing space for those, let's say, 500 names. And then we would have
gained nothing, since we need to allocate space for that temporary
storage.
