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.
