You have multiple CPUs, so a threaded process can theoretically reach
100*ncpus cpu usage.

Actually it doesn't. IMO, %CPU should be biased for all available

One problem is that method doesn't scale to lots of CPUs. On a Sun

I agree. The alternative is having a 10-thread process on such a system
report 1000% cpu utilization,
