[issue13517] readdir() in os.listdir not threadsafe on OSX 10.6.8

[Thouis (Ray) Jones]

Reading through many pages discussing readdir vs. readdir_r (many on security mailing lists, a large number referring to the page linked in the patch), I get the impression that most implementations are thread-safe as long as separate threads do not call readdir() using the same DIR pointer.

I believe there is some ambiguity in the POSIX specification as to whether this is the only way in which readdir() might be thread-unsafe.
