Example: limit CPU consumption to 10% for a math problem which ordinarily takes up 100% CPU:
bc -l <(echo "1234123412341234^12341234")
See the difference `prlimit` makes:
prlimit --cpu=10 bc -l <(echo "1234123412341234^12341234")
To actually monitor the CPU usage, use `top`, `sar`, etc.. or:
pidstat -C 'bc' -hur -p ALL 1
