[Python-Dev] My summary of the scandir (PEP 471)

I don't mind the idea of an "onerror" callback, but it's adding
complexity. Putting aside the question of caching/timing for a second
and assuming .lstat() as per the current PEP 471, do we really need
per-iteration error handling for readdir()? When would that actually
fail in practice?
