At least with the implementation I'm using (Frederic's 3.9-nohz1 branch), at least one CPU is forced to stay out of dyntick-idle *always*, even if all CPUs are idle. IMO, this is important to list as a known issue since this will have its own power implications when the system is mostly idle. Otherwise, document looks great.
