    We might want to allow multiple clients here. Otherwise only the least recent registered
client will receive updates.

> The JobClientActor assumes that it receives a job, submits it, and waits for the result.
This process should be broken up into a submission process and a waiting process which can
both be entered independently. This leads to two different entry points:
> 1) submit(job) -> wait
> 2) retrieve(jobID) -> wait
