removeChild .. removes from memory?

programming flash

Hi,
I am loading in a swf into my file, via the loader class. When I remove this child … does all the swf remain in the memory, or is it discarded? I want to remove it entirely …

var myLoader:Loader = new Loader();
myLoader.load("thisMovie.swf");
addChild(myLoader);

// bit and bobs later///////////////

removeChild(myLoader);

Thanks … … . . . . . … . . .
