Indeed, simply opening a file does not update the access time. So the poor
thing can be open-ed, read through mmap or sendfile-ed without atime being
modified -- as long as read() is not used.

I guess, open's behavior is standard -- at least, Linux behaves the same
way. Not sure if sendfile or mmap should act differently, though...

Thanks for the hint! Yours,
