any.)

When a CF object is created, it is CFRetain()ed and, thus, the collector will ignore it. If it is then managed entirely through a balanced set of CFRelease() and CFRetain() calls, it'll work just like it does under non-GC.


If you call CFMakeCollectable(), that'll effectively balance the CFRetain() at creation while making the collector aware of the object.

Thus, no real edge case here (as designed).
