--------------------------------------

This seems like a pretty easy candidate for multiprocessing.

> The CeleryExecutor doesn't currently support parallel execution to check task states since Celery does not support this. This can greatly slow down the Scheduler loops since each request to check a task's state is a network request.
>  
> The Celery Executor should parallelize these requests.
