Your nice 19 tasks receiving 'too much' CPU when there are other

(forgot to mention: if that's the case, you can add noautogroup to your
kernel command line to turn it off if distro turned it on in .config)
Thanks, Ubuntu's kernel is indeed configured with that option enabled,
and passing "noautogroup" at grub restores the previous behaviour. I'm
back to happy days again :) BTW, isn't this the "magic 200-line patch"
I was reading about ~2 years ago?
Yes.
