Hi all. I am wondering if anyone knows that maximum size of a AS3 program’s heap (free total memory)? I thought I read somewhere that Flash Player imposed some hard limit on this.

I have a SWF movie that needs LOTS (and I mean LOTS) of heap space to cache bitmaps (BitmapData objects actually). I monitor System.totalMemory to watch my memory usage and check for memory leaks. But there does not seem to be a similar variable/function to determine the amount of free total memory.
