Drop implementations that spawn async tasks (e.g. the drop in cursor executes a killCursors command) can panic if the tokio runtime gets dropped before they execute. This isn't a huge concern because usually the runtime is only dropped on application exit, but we should still try to exit more gracefully if possible.
