What did I do here?

q.js

var q = require('q'),
	guid = 1;


function randomDefer() {
	var defer = q.defer(), id = guid++;
	console.log("sending %d", id);
	setTimeout(function () {
		console.log("resolving %d", id);
		defer.resolve('hi');
	}, Math.round(Math.random() * 3000));
	return defer.promise;
}

var qs = [randomDefer(), randomDefer(), randomDefer(), randomDefer(), randomDefer()];

q.all(qs).spread(function () {
	console.log('value handler');
	console.log(arguments);
});

Output (doesn't matter whether I use .spread or .then):

sending 1
sending 2
sending 3
sending 4
sending 5
value handler
undefined
resolving 3
resolving 2
resolving 4
resolving 5
resolving 1

Ugh... Looks like I needed to return defer.promise. New output:

sending 1
sending 2
sending 3
sending 4
sending 5
resolving 1
resolving 3
resolving 5
resolving 4
resolving 2
value handler
{ '0': 'hi', '1': 'hi', '2': 'hi', '3': 'hi', '4': 'hi' }
