Until recently, if an event attempting to deliver an fd to a zombie object was demarshalled after the object was made into a zombie, we leaked the fd and left it in the buffer. If another event attempting to deliver an fd to a live object was in that same buffer, the zombie's fd would be delivered instead. This test recreates that situation. While this is a ridiculously contrived way to force this race - delivering an event from a destruction handler - I do have reports of this race being hit in real world code.
