Ah, OK.
> Well, it's a kernel change and, though not really complicated, it
certainly isn't a no-brainer either. So I don't quite agree that there
isn't any potential for breakage. Anyway, it's not like others don't break
stuff on a regular basis, and reverting the change is always an option.

Hmmm, I was thinking it would just be a userland libroot change which
called set_thread_priority and similar. I still think I could do it, but
having it as a kernel change is a bit more complicated indeed. So I may
just do it as a patch then, which I could later commit once it was
reviewed.
How do you do kernel work while actually running Haiku? I imagine it isn't
too safe to mess with the kernel on the running system. Could I test with
Qemu or similar? Or do you build onto another partition and test on that?
Pardon my ignorance on doing kernel-level changes. But while I did do some
kernel stuff in school it has been a while. But I'd like to get into some
Haiku kernel stuff though so this might be a nice start.
