On Python 3.5+, we can make use of scandir that not only list the content of the directory as an iterator but caches some infomations (for example, `is_dir()`; this avoid extra stats call to the underlying filesytem and can be – according to pep 471 – 2x to 20 time faster especially on NFS filesystem where stats call is expensive. From a quick this is the only place where scandir would make sens, as most other places only require the name. Fixes 1381
