I did say "runtime borrow checking" ie using them together. Example: `Rc::new(RefCell::new(value));`. This will panic at runtime. Maybe I should have used the phrase "dynamic borrowing" ?
You don't need different threads. I said concurrency not multi-threading. Interleaving tasks within the same thread (in an event loop for example) can cause panics.
