[TIMOB-19540] iOS: Ti.Network.HTTPClient does not work in synchronous mode in SDK 3.3.0+

	var url = "http://www.appcelerator.com";
	var client = Ti.Network.createHTTPClient({
		// function called when the response data is available
		onload : function(e) {
			Ti.API.info("Received text: " + this.responseText);
			alert('success');
		},
		// function called when an error occurs, including a timeout
		onerror : function(e) {
			Ti.API.debug(e.error);
			alert('error');
		},
		timeout : 5000 // in milliseconds
	});
	// Prepare the connection.
	
	// BUG:
	// This code is the sample code from the documentation simply added to the doClick function above.
	// The only change is to add the 3rd paramater [async] which defaults to 'true'.
	// When it is 'true', everything works fine, but when set to 'false', neither the onload() or onerror()
	// functions are called. This code works with SDK 3.2.3, but not with SDK 3.3.0 or 3.4.0.
	client.open("GET", url, false);
	// Calling with async set to true succeeds 
	//client.open("GET", url, true);

	// Send the request.
	client.send();
