In addition to what Kyle said, Olli landed a patch last year that makes us much lazier about hitting the purple buffer, because it isn't particularly cheap even with main thread CC, so we do it a lot less than we used to. You won't repeatedly add and remove an object that is being addref'ed and release'd. Instead, you add it once, then toggle a bit on the object itself saying whether it is really really something you should consider to be purple.
