This is just an idea, why doesn't someone hack the GC to never

Yes, that would be useful in telling us the *direct* cost of gc.
But there is some suspicion that the *indirect* costs of poor
memory locality is a bigger factor, and that is harder to measure:
Turning off the gc might make locality worse, making the results
hard to interpret.
But turning off gcc is a quick-and-dirty test, so it is probably
worth it anyway.
