It might in that case be worthwhile looking at using scandir() on
platforms that support that as well, so that other platforms can
benefit from an optimization as well. Though I'm not sure how much
that would actually help - ISTM that one actually scans the whole
directory anyway, just you don't have to do it yourself...
