What's the damage? ...of running that script in real time, CPU time, and memory usage

// @flow
process.send({ memoryStart: process.memoryUsage() });
const cpuUsageStart = process.cpuUsage();

const [node, harness, script] = process.argv;

require(script); // script can read process.argv themselves

process.send({ memoryEnd: process.memoryUsage() });
process.send({ cpuUsageEnd: process.cpuUsage(cpuUsageStart) });
