I vaguely wonder if we should make this a single "hardwareInterferenceSizes"
function, returning a std::pair<unsigned, unsigned>, because otherwise, when we
start add per-CPU tuning to the values, it's very likely to result in
duplicating the same series of conditionals in each of the two functions.
Also, with a single function, we are less likely to accidentally end up with an
override that returns values such that `destructive < constructive`.
