As you hint you already know, many people disable atimes for performance 
reasons.  But reasonably new kernels actually default to relatime or 
similar, I believe, so the performance issues are far less than they used 
to be.

You may also be able to do something with lsof and/or fuser, to check 
what files are actually open, but that won't catch files that are closed, 
only to be reopened again later.

But you can certainly blow away much of what's there at boot, especially 
if the mtime is older than your uptime.
