> Airflow worker currently becomes a celery process. Sending a SIGTERM to it performs a warm shutdown which waits for tasks to exit. We use runit which will send a SIGKILL after some time passes; the SIGKILL causes the airflow run commands to be orphaned (parented onto PID 1 init, celery does not know about them).
