what if ... we use atomic test-and-set to handle reference counting (with a lock for those CPU architectures where we haven't written the necessary assembler fragment), then implement a lock for each mutable type and another for global state (thread state, interpreter state, etc)?

Could be worth a try. A first step might be to just implement the atomic refcounting, and run that single-threaded to see if it has terribly bad effects on performance.
