Thanks, I agree, I expect this is Windows 7 or win32 specific.

Also, in creating a test case to demonstrate, I may have clouded my intent.
I want to walk() a dir, 
reporting the output of os.stat() for files below the dir.
One of the existing files happens to be named like "goo..."
And os.stat('goo...') fails to see the file.
I am not trying to rename the file, just hoping to stat an existing file.
