Does a listener still exist after its target object MC has been removed?

Question

Hi,
I have just a question about as3.0 programming (I suppose it
is the same for AS 2.0):
When a MovieClip is removed from the display list (either by
removeChild method or directly from within the stage from the
timeline), if listeners are running and attached to that object,
are they also removed, or do I have to remove them explicitly?
if yes, for a proper programming, I suppose that I have to
program a listener for the UNLOAD Event whose function will remove
all attached listeners, don't I?

It is called the DISPLAYlist and not the EXISTENCElist for a
reason. :)
=> yes sure :)
quote:
being eligible for garbage collection (gc) means it will be
removed from existence when memory usage of your swf increase
"enough" to trigger gc.
=> ok, I understand, but is there not any way to invoke
gc, to trigger it manually?
If you retake my example above, "playing!" seems to display
indefinetely, so it means that gc has not been triggered which may
be normal because memory hasn't increase dbut it is not handy
because the code in the clip supposed to be removed is still
running (even when clip is set to null). I persist and still don't
think it is normal :)
But I will study a lot more as 3.0, I think I should find an
answer in the interesting Colin Moock's book I am currently
reading, I am just at the beginning.
Thanks for your help!
