Add a new node to the dependency graph, to act as a single entry point before drivers are evaluated in parallel. The node will take all the driven RNA properties, and write their current value to the property again. This ensures that any implicitly shared data is copied to ensure writability. Subsequent concurrent writes by the driver evaluation will then be safe, as the thread-unsafe part has already been performed.
