Uncovered in tutorial party: osrf/ros2_test_cases#548
There was an issue where
ros2 doctor hello
would not shutdown on Windows, instead hanging with the trace:I believe this is because once the rclpy signal handler is installed, the KeyboardInterrupt was not getting triggered in the main thread. This makes it so that the executor thread will additionally call shutdown in the case that the signal is handled there first.
