thanks but i find your words more embarassing (there're all kinds of
smart people around) than flattering, i really don't need this ;P

since their engine executes original code with the additional policy
engine hooks, they may at most increase race windows, but they should
not add new ones. what their engine itself does in the presence of
threads is another question, i'd like to see how they can remain
performant yet protect their own memory against modification (normally
that's a round-trip to mprotect/VirtualProtect and suspension of all
other threads).
