As a compromise, would it make sense to make the atime granularity adjustable? I.e. instead of the default microsecond granularity use a 1-second granularity. Or a 10-second granularity, so that the atime would be adjusted only once per every 10 seconds. And similarly for mtime, though here you should obviously be more careful. -SB
