It's not like I'll get a choice between the task database going down and not going down. If my task database goes down, I'm either losing jobs or duplicating jobs, and I have to pick which one I want. Whether the downtime is at the same time as the production database or not is irrelevant.

In fact, I'd rather it did happen at the same time as production, so I don't have to reconcile a bunch of data on top of the tasks.
