So I read the other article, and I saw that bit that disagreed with my essay. My first thought was, "Oh, of course that's how it works. How did I get that so wrong?" My only excuse was that this essay was originally a tech talk and I was under a deadline. (But I really should have caught it when I wrote it up as an essay.)

So I was going to go edit my essay, when I learned that my essay was also posted on Hacker News. And now I discover that someone has already called out my error before I could fix it. Sigh.

Anyway, I just thought I should acknowledge this before I go to fix it.

Thank you so much for responding! I really appreciate you clearing this up for me.

And don't beat yourself up too much. This was a phenomenal article and it gave me the courage to dig into the kernal code myself.

And kudos to you for following up with your own exploration. It's so often the case that the most interesting stuff is hidden in what other people are wrong about.
