System.totalMemory / unload / IE (2 questions)

Question

hello guys, i ve been playing with AS3 from a while and i
noticed 2 things
after a huge search i could find my answers, so tell me what
do you think please.
1/ i am trying to load images and monitor the
System.totalMemory i noticed that even if i unload and remove the
listner and give it 500 ms so the GC do its job but the unloaded
images data are always there... please see the attached file u ll
notice that the totalMemory (in the FLASH DEV ENVIROMENT) increase
and increase and this is a small image what about if i am loading
huge images...
2/ talking about huge images well replace the img.jpg with
something bigger and open your performance monitor and run the html
page in IE notice that the memory consumed by the IE page increase
and increase and never stop (its LIKE in the FLASH DEV
ENVIROMENT)... but in FF or swf its ok .
so the question here is the unload remove the data or what?
or am i doing something wrong that make the GC never remove the
data. And how would i manage the IE issue??

Hi,
I also facing the same memory problem.
As you said in this case it works fine. But my case i am not
loading images instead i load swf file which has sound embeded to
the timeline as stream.
According to this code, same memory management performs well
for me also. but the sound in the unloaded swf is still audible and
when i load the next swf, these all sounds mix up and i don't hear
anything properly.
To avoid the sound problem i added a line
SoundMixer.stopAll() to getaway the problem, but after i added this
line memory management got lost and my system gets hanged.
import fl.controls.List;
import fl.data.DataProvider;
var tl:MovieClip = this;
var loader:Loader = new Loader();
var myList:List=new List();
var dp:DataProvider=new DataProvider();
tl.addChild(loader);
addChild(myList);
function loadNext(e:Event) {
//loader.unload();
loader.contentLoaderInfo.removeEventListener(Event.INIT,loadNext);
tl.removeChild(loader);
loader = null;
loader = new Loader();
tl.addChild(loader);
var o=new Object();
o.label=String(Math.floor(System.totalMemory/1024));
dp.addItemAt(o,0);
myList.dataProvider=dp;
setTimeout(loadNow,100,null);
//start loading
function loadNow(e) {
loader.contentLoaderInfo.addEventListener(Event.INIT,loadNext,false,0,true);
loader.load(new URLRequest('img.jpg'));
loadNow(null);
