No, since they have a different scheduling policy than all normal niced
processes and don't behave like nice -20 (nice = +20) processes.  They
sort of behave like nice -21 through nice -52 processes.  top(1) has a
hack which are supposed to display them as having the fake nice values
21 through 52, but it is broken in -current by much the same kernel
changes that break the display of rtprio values in ps(1) (see my other
reply to this thread).
