According to the docs, you should be able to pass timeout when doing new Script. This seemingly does not work.

Running the following snippet will successfully throw an error after one second:

const vm = require('vm');

const script = new vm.Script('while(true){}');

script.runInContext(vm.createContext(), {timeout: 1000});

The following will not:

const vm = require('vm');

const script = new vm.Script('while(true){}', {timeout: 1000});

script.runInContext(vm.createContext());

I did some digging (which might not be useful at all), and to my untrained eyes it looks like new Script constructor ignores timeout argument:

node/lib/vm.js

	produceCachedData = false,
	[kParsingContext]: parsingContext
	} = options;

the docs are wrong in this case (displayErrors should also not be listed), would you care to open a pr? its fine if not.

That's a shame!

Sure, I can send a PR for that
