[New-bugs-announce] [issue13757] os.fdlistdir() should not close the file descriptor given in argument

[Charles-François Natali]

New submission from Charles-François Natali <neologix at free.fr>:

os.fdlistdir() closes the FD passed as argument.
This is annoying, since in 99% of the cases you'd like to keep FD intact, so you end up doing os.fdlistdir(os.dup(fd)).
Here's a patch that duplicates the FD in fdlistdir(), so that the original FD is kept intact, which is much more natural (at least to me :).
That's an API change, but since fdlistdir() has been introduced in 3.3 which hasn't been released yet, I think it should be acceptable.
