- Add test_flow_with_rlock_in_state to verify Flow works with threading.RLock in state
- Add test_flow_with_nested_unpickleable_objects to verify Flow works with unpickleable objects nested in containers
- These tests ensure the issue from version 1.3.0 (TypeError: cannot pickle '_thread.RLock' object) doesn't get reintroduced
- The issue was resolved in the current main branch by removing the _copy_state() method that used copy.deepcopy()
- Tests verify that flows with memory components or other resources containing locks work correctly
