Yes, I saw that doc (also in Qt4). What kind of sharing does this refer to - across threads and/or only across owners in a same thread? ObjC's reference counting basically determines the lifetime of an object (and prevents the need for a "deleteLater" operator). But the main thing I'm curious about: is this implicit sharing mechanism thread safe and if so, do you (thus) use some kind of interlocked increment/decrement of the reference counter? Cheers, René
