Less precise, but it       can be done without fancy        hardware.              Mostly I was hoping somebody had already done this experiment. If they had       reached the conclusion that NOPs do help, it then becomes a question of why       different experiments reached different conclusions.              I wasn't able to find any evidence while researching the question initially,       but before I moved the "accepted answer" check I figured I'd ping the world       again to see if this was ever more than a rumor.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
