You know you can catch TLB misses on some real x86 processors I assume ?

(You load the page table entry as missing then when you take the trap you
 put the entry in, touch the page to load it, and then mark it missing again)

Hi Alan,

The use of the page table traps might be faster than the valgrind simulator. It also might simplify some of the analysis; valgrind has a lot of additional pages for the binary translation. However, the valgrind simulator does everything in user space and avoid needing root access on the machine.
