New submission from whitespacer: When pathlib mkdir is called with parents=True and some parent doesn't exists it recursively calls self.parent.mkdir(parents=True) after catching OSError. However after catching of OSError and before call to self.parent.mkdir(parents=True) somebody else can create parent dir, which will lead to FileExistsError exception.
