Trampolining "memory leak" on ES6 recursive promise resolve chain.

	const promiseYoullWork = () => Promise.resolve();

	async function job(todo: number, iterations: number = 0): Promise<number> {
	// Print memory consumption of the process every 10k iterations
	if (iterations % 10000 === 0) {
	const memUsage = process.memoryUsage();
	const mem = (memUsage.heapTotal / 1024 / 1024);
	console.log(`i: ${iterations / 1000}k`, `mem: ${Math.round(mem * 100) / 100} Mb`);
	}
	if (iterations === todo) {
