Ah, you're right.  I misread the define and saw "IO" inside "PRIO" and
my brain fixated on that. :)

I actually think it could possibly have a similar problem though if the
scheduler never gave the process time if another one was pegging the
CPU.  Maybe Robert could shed a little light on this, he's the resident
kernel expert. :)
