Side note: a lot of the mtime/ctime/atime rules are really pretty arbitrary. They've grown over time, and have various historic reasons. 'ctime' in particular is more arbitrary than most, and I don't at all guarantee that all Unixes will work exactly the same wrt ctime and rename.

In fact, I -can- guarantee that some older versions of Linux haven't always updated ctime on renames, for example, and it's probably still per-filesystem.
