GC notification is triggered *after* objects are removed, so even if that were to work*, it'd be nil at the time the executor got around to being notified. For "about to be" instead of "was just" GC'd, you'd need Ephemerons, not finalization. Removing a class you're an instance of might be a bit fishy as well. (as I understand were to be the case if you only implement #finalize), though it'd be nice with some details why it "didn't work out" for Johan. Working around that would be specifying a custom #executor instead of #finalize, returning an instance of a separate class, with a slot for the class to be removed when triggered. (That executor class would have to implement finalize, of course) Cheers, Henry * The ref would have to be held through a weak array, otherwise the executor would have a strong reference to the object, and it'd never be garbage collected in the first place... Image Roots -> WeakReg -> Executor -> MyObj
