As usual, my suggestion is to restructure all sorts of things I don't understand....
Maybe you could store atimes in a compressed sense; Make a struct with just atimes and inode numbers, and pack them into a page of memory. You could stuff a lot of atimes away before they took up much space.
Even assuming you put -half- of the memory to pointers for some kind of data structure (much more than necessary), you could look at 7,000 files and still only have 1 meg of atimes 'constipated away'.
