Frames aren't objects in memory; they are just concepts. (Key)frames are simply time markers when actions occur. Some of these actions are authored as ActionScript code; others are authored graphically, but the latter are the equivalent of writing addChild() and removeChild() statements to the MovieClip. There is one display list that has things added and removed (or transformed or Tweened) as the playhead advances. Objects removed at any key frame therefore should be eligible for garbage collection, assuming no event listeners or other code created a reference to them.
