Other OopHandle releases are for data that is deallocated or not reused so zeroing _obj is not needed in those places.  I didn't want to zero _obj in OopHandle::release anyway without zeroing it in the analogous WeakHandle::release. WeakHandle release code operates on const objects, also which are deallocated after release.

Seems odd that there is not a way to NULL the pointer directly - why is it not done as part of release()?
