I've been meaning to make a generic wrapper for any utility, where the wrapper parent watches the load balancers, and the child does its work at full speed, but the parent will occasionally SIGSTOP/SIGCONT it...... haven't got around to that yet. The generic wrapper could even have another pluggable-child as its rate-limit determiner, so anybody could use it.
