[New-bugs-announce] [issue27086] Add closefd argument to os.listdir

New submission from Evgeny Kapun:

Currently, when given a file descriptor, os.listdir will duplicate it so that the original file descriptor is not closed. In many cases, a file descriptor is not needed anymore after directory is listed, so this is not necessary. I propose adding a keyword argument closefd to os.listdir which, if set to True, will make os.listdir take ownership of the passed file descriptor and close it at the end.
