Tim Caswell's Fiber idea implemented with Mozilla Javascript 1.7 generators

fiber.js

/* in this case, there is no explicit wait() function, instead, fiberized functions use the yield keyword */
module.exports = function(generatorFunction) {
	var iterator;
	function resume() {
		iterator.send(arguments);
	}
	iterator = generatorFunction(resume);
	iterator.next();
};
