You could go a bit further and have multiple concurrent threads mark the references, then sweep them up in a separate thread, too. Some sort of concurrent sweep and mark reference count system.

With concurrency you need atomics or locks to synchronize reference counts between cores, unless you can somehow guarantee that ref counts only decrement and can never increment.
