As I have read from earlier replies, ext2/3 replaces a filename with the new one, given that it is the same length or shorter, and especially that might skip a while when readdir()ing. So I was concerned about the speed impact which would arise, if the filename was never modified in-place but always appended as a new object to the end-of-directory.
