Generally, the atomic Edition needs to have a lock if you want to ensure thread security, and in addition is bumping the ref count on the article (as well as autorelease depend to stability it) in order that the object is sure to exist to the caller, in any other case There's a possible race affliction if A different thread is setting the value, triggering the ref rely to drop to 0.
