It only has an effect when you don't have atomic reference counting built-in, in which case it toggles whether it'll use a mutex to make sure ref/unref and thread safe. If you have atomic ref counting built in then then you can't change it, it's always thread safe as the cost of adding an if statement would be more expensive than just doing the atmoic increment/decrement.
