### Handling Loader Unload Events in Child SWF

Source: https://github.com/greensock/greensock-as3/blob/master/src/com/greensock/loading/changelog.txt

This snippet demonstrates how a child SWF can listen for the LoaderEvent.UNLOAD event to perform cleanup. This is useful for managing stage event listeners, sounds, or NetStreams to prevent memory leaks.

```ActionScript
var curParent:DisplayObjectContainer = this.parent;
while (curParent) {
	if (curParent.hasOwnProperty("loader")) {
	    Object(curParent).loader.addEventListener("unload", dispose, false, 0, true); 
	}
	curParent = curParent.parent;
}

function dispose(event:Event):void {
	//cleanup code here...
}
```
