When a listview inside a scrollview uses a loader in async mode, there is a meltdown.

It does not appear in Loader.asynchronous: false, only true.

You must change the scrollbar rapidly enough to cause it to fail.

When you try to close the test app, you get the warning:

"There are still \"187\" items in the process of being created at engine destruction."

A copy of the test project is attached.
