Can you use a weak pointer to do what you want? If you keep a weak pointer to the head of your expensive list then itwill be reclaimed at the next major GC I believe. I have used weakpointers for vaugely similar purposes before. I guess a downside is that they will always be reclaimed on GC even ifthere isn't memory pressure, I think.
