We should kille the load avarage as a measure for system activity,
it only has any relevance if you run heavy CPU bound processes.
If the majority of your threads yield their quantum, load average
contains absolutely no information of any relevance to system
capacity.
Try this:
main()
for (i = 0; i < 10000; i++)
start thread {
calculate time until top of next second
sleep (until then)
}
You'll see a monster load-avg on idle cpus.
