Well, I guess it boils down to whether we want to support this function (which should be easy, I think), or support filesystems without atime. I vaguely remember that many filesystems don't have (or are capable of disabling) atime for performance reasons, but I could be wrong. But, if that's true, it may make sense to sacrifice the session-readonly functionality in order to support non-atime compliant filesystems. It should be a one character fix, if we decide to do it :)
