QTKit creating threads that never die when I play new movies

I have an app that composes movies and then plays them via QTMovieView. Each time I [movieView setMovie:newMovie], QTKit creates a开发者_如何学Go new thread that never dies. It also appears that the movie is never dealloced. I created a simple example that illustrates the problem:

I will happily pay someone to solve this problem!

You have a big fat memory leak in this method:

-(void)restartMovie {
    QTMovie *m = [movieView movie];
    [m stop];
    [movieView setMovie:[m copy]]; // <- copy creates an object THAT YOU OWN!!!
    [movieView play:self];
}

so this behavior is expected.
