DOMException when rendering the grid multiple times within a short amount of time

[zernyu]

This is probably the same issue as: #81

If you go to http://sitepen.github.com/dgrid/dgrid/test/JsonRest.html and type this into the console:

for (var i  = 0; i < 10; i++) {
    grid.refresh();
}

you'll get flooded by DOMExceptions.

I've temporarily "fixed" this by modifying whenDone() in renderArray() of dgrid/List.js to look like this:

function whenDone(resolvedRows){
    // Fix for DOMExceptions caused by querying the grid too fast
    try {
        (beforeNode && beforeNode.parentNode || self.contentNode).insertBefore(rowsFragment, beforeNode || null);
        lastRow = resolvedRows[resolvedRows.length - 1];
        lastRow && self.adjustRowIndices(lastRow);
    } catch (exception) {
        if (!exception instanceof DOMException) {
            console.error(exception);
        }
    }
    return rows = resolvedRows;
}

I have a feeling this might lead to memory leaks. Hopefully someone can come up with a better solution!

swiftdemise,
just so you know, http://sitepen.github.com/dgrid/dgrid/test/, is totally not up to date. It's better to pull a local copy from master. Not saying that you won't find the same problems, but testing against that location won't help at all :)

Yep I know that. My project is running master and I wanted to demonstrate the issue and it turns out the test page has the same behavior.

This should be fixed with #103. If you still have problems, let us know. Thanks!
