This sounds fragile and potentially wrong. Also, spinning wastes CPU time. If you run Factor in one thread and your C code in another, then you should be able to just use pthread mutexes. Use the Factor FFI to bind to the pthread API, and put a lock inside your struct. Take the lock when you modify it.
