(Wrong) CPU utilization reported by top

[Václav Haisman]

Hi,
I have noticed that top reports strange values for CPU utilization. The
problem is that while it reports this for overall utilization...

CPU states: 40.8% user,  0.0% nice,  3.7% system,  4.5% interrupt, 50.9% idle

...it doesn't show a single process that would have over 1% of WCPU or CPU!

  PID USERNAME         THR PRI NICE   SIZE    RES STATE    TIME   WCPU COMMAND
17980 xxxxx              1  96    0  5568K  3536K *Giant 213:05  0.00% silc

I am quite positive it is the vlc process that eats most of the reported 40%
of CPU because if I turn it off the user time goes down bellow 10%. But
despite that top shows zero in its row.

The box is uniprocessor x86 FreeBSD 6.1.
