I hadn't paid much attention to these labels, but I saw kaizen and wondered about that.

Right, you have to do this, because the architecture of the computer requires it. So you might go around optimizing things with seemingly no effect, until it gets good enough to fit in a cache line.

"Kaizen (Japanese: 改善; "improvement") is a Japanese concept in business studies which asserts that significant positive results may be achieved due the cumulative effect of many, often small (and even trivial), improvements to all aspects of a company's operations."

That's why I often advocate for things that only show up in pprof. But I am not a "zen" person. l am a pre-zen animist person.

Right. I haven't been enforcing that rule, but I should. So I renamed your PR ;)
