Dear Maintainer,
I had time to compile it and did sometesting.
It turns out, that the total value exceeds the 32bit unsigned data size
of gulong:
$ while true; do grep "^cpu " /proc/stat; sleep 0.5;done|awk '{ used=$2+$3+$4+$7+$8; total=used+$5+$6; printf "used=%ld total=%ld load=%ld\n",used,total,256*(used-prevused)/(total-prevtotal);prevused=used;prevtotal=total}'
used=121149519 total=4480532061 load=6
used=121149529 total=4480532362 load=8
used=121149537 total=4480532651 load=7
used=121149547 total=4480532929 load=9
used=121149557 total=4480533268 load=7
used=121149568 total=4480533570 load=9
used=121149577 total=4480533821 load=9
used=121149590 total=4480534188 load=9
cu, Stefan
