I see... but if I need to proactively remove an object from a cache in dealloc, this creates a very unfortunate dependency between the object and its cache... something I would like to avoid altogether :/ Any idea about how to implement a generic weak cache mechanism which doesn't depends on any help from the objects it's holding to stay valid?

What about a cache which retains its objects as usual, but periodically checks their retain counts and release them when there's only one reference left?

That is almost exactly how MPWFoundations's oject-cache works.
