On a separate note, since atime updates are not usually very important anyway, why not have an option to cache atime updates for a long time, or until either a write occurs anyway. Holding a large number of atime updates in a write cache is generally not going to be a major issue - the worst case if a partition isn't cleanly unmounted is that some atimes will be wrong.
