Does this mean it's not possible to implement an async version of
os.walk() if we had an async version of os.listdir()?
I.e. for async code we're back to implementing iterators "by hand"
instead of using generators for it.
For now yes. Unfortunately, we don't have time to implement
coroutine-generators properly in 3.5.
Thanks,
