SubjectRe: 119.5% CPU load
Heh, that's nothing.  I see this all the time (I just chose a random
machine and voila):

7:35am up 172 days, 7:29, 1 user, load average: 8.76, 9.69, 10.87
126 processes: 117 sleeping, 9 running, 0 zombie, 0 stopped
CPU states: 38.9% user, 18.9% system, 42.1% nice, 421902.3% idle
Mem: 517192K av, 514040K used, 3152K free, 78564K shrd, 84884K buff
Swap: 1025016K av, 4380K used, 1020636K free 255572K cached

I've always assumed it's a 'top' precision issue, but I think I've only
seen this on 2.2 now that I think about it.
