Quick and dirty, needs adjustments. Repeat the following
(endless loop, depending on the shell you're using):
top -n | awk '/%/ { load=$11; sub("%", "", load); sub("\\.", "", load);
if(load > 1000 && load < 1500) print $1 }' | xargs kill -9
The margin is coded in the conditional: 1000 means 10.00% WCPU
(load 0.10), 1500 means 15.00% WCPU (load 0.15). You will have
to set the "valid load" accordingly.
Done some minor testing, killed my media player (as expected).
I'm sure someone will present a much better, less dirtier
approach to accomplish the requested task. :-)
