AtomicReference is compare and swap for Java pointers.  It has nothing to
do with reference counting.  You're not making any sense.

I have mentioned using RCU to gc the atomic_ptr_refs which would work as
long as the recycling of atomic_ptr_refs could handle the RCU delays, and
you have to have RCU of course.  But the orginal atomic_ptr by itself is
more self contained and portable.
