Resources are shared, when running multiple contexts on the same thread. Cycles uses the same context on multiple threads and expected same resources. This change will introduce a single render graph per context and an updated resource management. Render graphs are not shared anymore; Resource pools are still shared, but garbage collection depends on the thread and if background rendering is used.
