[replying to python-dev this time]

The "onerror" approach can also deal with readdir failing, which the PEP currently glosses over.

Do we want this, though? I can see an error handler for individual entries, but if one of the *dir commands fails that would seem to be fairly catastrophic.

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.
