[python-win32] Size of directory

The above uses os.listdir(), which I've had problems with in the past with
huge directories (I can't recall, but I suspect it was simply performance
that sucked).  Either way, the fastest I've come up with has been based
around:

    for fd in win32file.FindFilesIterator(os.path.join(dir, "*")):
        name = fd[8]
        if name in ('.', '..'):
            continue

See the docs for how the 'fd' tuple is laid out.

Cheers,
