[Python-ideas] Speed up os.walk() 5x to 9x by using file attributes from FindFirst/NextFile() and readdir()

Yes, you're right. The amount of information in st_mode would be
implementation dependent. I don't see a huge problem with that -- it's
already true for os.stat(), because on Windows stat()'s st_mode
contains a much more limited subset of info than on POSIX systems.
