Counterpoint: possibly OpenBSD doesn't really have any relevant 'kernel processes' (in line with the model: the kernel is there to serve user-mode, and not a goal on its own). (And tangentially: why do I need multiple `psimon` kernel processes? Tire pressure is good to keep in mind, I guess, but, at the kernel level? Repeatedly?).

I truly don't know, by the way; this was merely an example to illustrate my perceived difference-in-complexity between Linux and OpenBSD, which might be entirely misguided, but definitely part of the issue the article linked in the submission hints at?
