At the current rate of cache flushes (way way too high), the main factor wrt
performance is indeed the execution of the instructions.

As soon as we've implemented page colouring (which turns out to be really very
close to large page support), I expect us to get along with very very few
cache flushes - basically I hope we can avoid them completely.
