Very much agreed that this isn't necessary for just readdir/FindNext
errors. We've never had this level of detail before -- if listdir()
fails half way through (very unlikely) it just bombs with OSError and
you get no entries at all.

If you really really want this (again very unlikely), you can always
use call next() directly and catch OSError around that call.
