Alloy ListView Memory Leak

MacOS 10.9, SDK 3.2.0, Alloy 1.3.0

Hi,

I have been running some instrument tests on a simple ListView in iOS using a template and a small number of generated rows

Index.xml is

<Alloy>
    <Window class="container">
        <Button id="reloadButton" onClick="doClick" title="Load List" height="30" top="25"/>
        <Button id="clearButton" onClick="doClear" title="Clear List" height="30" top="5"/>
        <ListView id="testList">
            <Templates>
                <ItemTemplate name="myItem" id="myItem">
                    <Label bindId="title" id="title" />
                    <Label bindId="value" id="value" />
                </ItemTemplate>
            </Templates>    
            <ListSection id="mySection" />
        </ListView>
    </Window>
</Alloy>

and the index controller is

// clear the list
function doClear(e){
    $.mySection.setItems([]);
}
 
// reload the listview
function doClick(e){
 
    var items=[];
    for(var i=0; i<4; i++){
        items.push({
            'template': 'myItem',
            'title':{'text': 'aaaaaaa'},
            'value':{'text': 'bbbbb'}
        });
    };
 
    $.mySection.setItems(items);
 
}
 
$.index.open();

index.tss is

".container": {
    backgroundColor:"white",
    layout: 'vertical'
},
 
"#myItem":{
    height: 80
},
"#title":{
    font: {fontSize: 14, fontWeight: 'bold'},
    color: 'red',
    left: 15,
    top: 5,
    height: 20,
    right: 15
},
"#value":{
    font: {fontSize: 12, fontStyle: 'italic'},
    color: 'blue',
    left: 15,
    top: 20,
    height: 20,
    width: Ti.UI.SIZE   
}

And the results(Living) each time I do a load and then a clear are:

TiUILabelProxy:   8,8,12,12,16,16
TiIListItemProxy:  4,4,6,6,8,8
TiUILabel:            8,8,12,12,16,16
TiUIListItem:        4,2,4,2,4,2

Now while the actual ListItem seems to clear, everything else just builds up and although this is just a test I have a complex iOS/Android app that I am nearing completion of that uses ListView exclusively.

I am now wondering if this apparent leak is going to cause a problem with the complex templates that I am using in the app.

I have tried other ways of removing the list items ( i.e. deleteItemsAt etc.), but nothing seems to make a difference.

It looks to me like the Label components in the template are the issue here, but is there a correct way of releasing the memory that appears to be building up using the List Item Templates the way I am?
