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

[Vetoshkin Nikita]

Vetoshkin Nikita <nikita.vetoshkin at gmail.com> added the comment:

Glibc's readdir() and readdir_r() already do caching, so getdents() syscall is called only once on my '/etc' directory. Should we include another caching level in xlistdir() function?
On the other hand, we don't know anything about caches at glibc's level, i.e. we can't tell if our next call to readdir() will result in syscall or even I/O (we could possible release GIL for that).
