walk() is implemented using listdir(), so I believe the documentation here
is right. Here's the relevant code from os.walk():

    try:
        # Note that listdir and error are globals in this module due
        # to earlier import-*.
        names = listdir(top)
    except error, err:
        if onerror is not None:
            onerror(err)
        return

As you can see, if listdir() throws an exception, it is ignored unless
"onerror" is specified.
