We must also be clear what the requirements are.
Suppose you are GotRocks Inc and can have lots of processors and lots of
storage but you must finish 90% of transactions in 1 second and the rest in
10 seconds. Suppose you are looking at a back end database server.
Now the costs of reference counting can be beaten by having more
processors. But the costs of collection are a huge lump right where it
hurts. Collection can only be subdivided so far because of cross pointers.
