Subject: 2.6.30 BUG? Full load, but nice levels cause CPU idle time?

I'm not subscribed, so please include me in the CC on this.

I'm running 2.6.30 (gentoo).  I have a quad core (Intel Q9450), and I
have four CPU intensive processes running.  Three of them are set to
nice +5, while one is at +0.  When I look at the CPU load in top, I
find that the +0 gets 100% of a CPU to itself.  The three +5's are
sharing two CPUs, leaving the fourth CPU completely idle.

Is this supposed to happen?  It seems to me that if there's work to
do, no CPU should be left idle, right?

Thanks.
