Overview

Used internally by rmext_on_dealloc. The idea is this object is added to the object we want to watch for deallocation. When the object we want to watch is about to dealloc, this object will dealloc first, so we can execute the block. the object it follows is kept only as a weak reference to not create a retain cycle.
