When connecting a signal to the same anonymous function repeatedly, a new GlobalReceiverV2 object would be created after each call. Each GlobalReceiverV2 would have a unique callback object despite all these callback objects sharing the same code. This would lead to a large number of GlobalReceiverV2 and callback objects, each never reaching a refcount of 0 and thus never being released. The remedy is that we only need one GlobalReceiverV2 object, whose corresponding GlobalReceiverKey references not the outer callback object, but the code object associated with it.
