my application loads sub-apps at run time. The usual work is user click action button load sub-app swf, perform
whatever he need to perform and close it. On closing event main app unload sub-app and remove it from display list
so memory occupied by sub-app will be returned to the pool. However sometimes user want to load
several sub-app at same time. So, main app has to track available FP memory at least for rough estimate.
I believe System.totalMemory() returns total memory used by all Flash apps running in this browser.
But I seems can't find a way to get total memory FP allocates in order to compute available memory.
I understand that this technique of available memory computation does not work well or sometimes does
not work at all. But maybe someone run into similar issue and gave a deep thought to it based on some
kind of heuristic approach.
