Perhaps it's a good chance to revisit the functionality. Right now the UI "run" button actually runs the task via CeleryExecutor. Perhaps instead (or just when using a non-Celery executor) it should queue the task and let the Scheduler pick it up. I guess in that case it would just be sugar for marking a TI as QUEUED. Just a thought.
