Performance was not the original motivation for my suggestion to persistance, 
but only about improving profiling ability of valgrind itself (either with 
OProfile or self hosting).

Why do you need function level consistency checks? Checking the modify date of
a shared object should be enough when separating TCs by objects. You usually 
do not have self-modifying code in read-only pages backed up by files.

And I am not sure whether the issue about absolute addresses generated by the 
binary translation engine does happen with VEX.
