Description

The proxy objects are never being collected by the V8 engine. We appear to be using Persistent handles, but never make them weak or setup callbacks to properly dispose of them once the JS object is unreachable.

Test Case

setInterval(function() {
  Ti.UI.createView();
}, 500);

If you run the above test case and monitor the memory usage, you will see it continue to go up with out any collections.

Here's another test case which opens / closes a window with a bunch of labels:

   var win = Ti.UI.createWindow();
   
   function openWin() {
   	var win = Ti.UI.createWindow({
   		backgroundColor: 'red'
   	});
   	
   	for (var i = 0; i < 100; i++) {
   		var label = Ti.UI.createLabel({
   			text: 'Label #' + i
   		});
   		win.add(label);
   	}
   	
   	setTimeout(function() {
   		win.close();
   		win = null;
   	}, 1000);
   	
   	win.open();
   }
   
   setInterval(openWin, 3000);
   
   win.open();

Verified the fix by running the test code provided & its working as expected. Thus closing.
