Yes. I used to take some shortcuts in the past that always marked pages
accessed and dirty (if necessary) to eliminate code in the tlbmiss
handler.
Paulus made me fix that, so page stealing and swapping would work
more effectively. However, I'm still considering making a configuration
option because on embedded systems where the stealing and swapping
don't occur you shouldn't have to pay the price of the management in
the tlbmiss handler.
