The problem is that the following code might or might not work, depending
on the behavior of the browser's GC:
url = createObjectURL(blob);
blob = null;
setTimeout(function() { img.src = url; }, 0);
If the timer executes before GC collects the blob, this works, because the
URL is still valid. Otherwise, it fails, because--since the Blob no longer
exists--the URL is no longer valid.
