How to create a simple memory leak with Titanium

app.js

var memLeakArray = [];

function FirstWindow() {
	var win = Ti.UI.createWindow({
		backgroundColor: '#ccc'
	});
	
	var btn = Ti.UI.createButton({
		title: 'open next',
		width: Ti.UI.SIZE,
		height: Ti.UI.SIZE
	});
	
	win.add(btn);
	
	btn.addEventListener('click', function(){
		SecondWindow().open();
	});
	
	return win
}

function SecondWindow() {
	var win = Ti.UI.createWindow({
		backgroundColor: '#ccc'
	});
	
	var btn = Ti.UI.createButton({
		title: 'close',
		width: Ti.UI.SIZE,
		height: Ti.UI.SIZE
	});
	
	win.add(btn);
	
	
	for(var i = 0; i < 20; i++) {
		var l = Ti.UI.createLabel({
			top:0,
			text: 'meh'
		});
		// Memory Leak!!!
		memLeakArray.push(l);
		win.add(l);
	}
	
	
	
	btn.addEventListener('click', function(){
		win.close();
	});
	
	return win;
}

FirstWindow().open();

Can't crash the app isn't it?
