Would "weighted reference counting":
   http://www.cs.kent.ac.uk/people/staff/rej/gcbib/gcbibJ.html#jone92
be any speed advantage for multi-threaded smart ptrs?
It's supposed to avoid synchronization for copy and only
requires synchronization for decrement of reference count.
The cost is extra memory in the pointers.
