[New-bugs-announce] [issue11406] There is no os.listdir() equivalent returning generator instead of list

[Марк Коренберг]

New submission from Марк Коренберг <socketpair at gmail.com>:

Big dirs are really slow to read at once. If user wants to read items one by one like here:
--------------
for i in os.listdir()
    use(i)
--------------
having generator will gain performance, as big directories often very fragmented on disk. Also, dir_cache in kernel used more effectively.
