[Python-Dev] Issue 11406: adding os.scandir(), a directory iterator returning stat-like info

Thanks. I take it those are "USING FAST C version"?

What is "-o cache=no"? I'm guessing the last one isn't giving dirents,
so my version is slightly slower than the built-in listdir/stat
version due to building and calling methods on the DirEntry objects in
Python. It should be no slower when it's all moved to C.
