It turns out to be fiendishly difficult to automatically elide counter bumps.

They can produce a working ref counting solution.

D's will have a couple fundamental advantages over the C++ one:

1. D won't need the locking on the increment, because D has different types for 
threaded vs non-threaded.

2. With dip25 and dip1000, D can offer memory safe access to rc object contents.
