Just to give a reason to that: on many systems you can have bitflips 
with far less than 1 or 2 million cache misses.
https://users.ece.cmu.edu/~yoonguk/papers/kim-isca14.pdf reports as 
little as 139K accesses (-> cache misses) to be sufficient on one of 
their systems and on one of my systems I can have a bit flip with as 
little as 78K cache misses (double sided hammering).
