- /// duration of the remove_from_owner call. This may not be a problem in
- /// this limited example, but in multithreaded programs remove_from_owner
- /// may be called from a different thread to the thread which manages the
- /// owner's lifetime.
- /// - ACE_Weak_Bound_Ptr (Gadget_ptr) has no ownership semantics, so we have
- /// no circular ownership problems. Weak pointers can also be converted
- /// back into strong ones, so it is possible to guarantee the lifetime of
- /// the owner object for the duration of the remove_from_owner call.
