What should occur if `shutdown()` is called multiple times (potentially with different values for `immediate`)? Looking through the PR implementation currently, it seems like it could be possible for a second call to unset the immediate state while threads are waiting, causing some threads to raise the shutdown exception while others continue to `get()` items until the queues are empty. Perhaps `shutdown(immediate=False)` should be a no-op if the state is `shutdown-immediate` already? --- _[View the full topic](https://discuss.python.org/t/queue-termination/18386)._
