FR Passed: Memory leak seems to be contained using the following test case.

var win = Ti.UI.createWindow({
	backgroundColor: '#fff'
});
 
var btn = Ti.UI.createButton({
	title: 'Trigger'
});
var count = 0;
btn.addEventListener('click', function () {
	var url = 'https://www.mediawiki.org/w/api.php?action=help&recursivesubmodules=1';
	var xhr = Ti.Network.createHTTPClient({
		onload: function (e) {
			Ti.API.debug(this.responseText);
			// alert('success');
			console.log('Success');
			count++;
			// $.num.text = count + ' calls';
		},
		onerror: function (e) {
			Ti.API.debug(e.error);
			console.log('error');
			// alert('error');
		},
		timeout: 5000
	});
	xhr.open('GET', url);
	xhr.send();   
});
 
win.add(btn);
win.open();
