data to the parent process (usually created by running `compare.js`, `run.js` or
`scatter.js`).
### v8ForceOptimization(method[, ...args])
Force V8 to mark the `method` for optimization with the native function
`%OptimizeFunctionOnNextCall()` and return the optimization status
after that.
It can be used to prevent the benchmark from getting disrupted by the optimizer
kicking in halfway through. However, this could result in a less effective
optimization. In general, only use it if you know what it actually does.
