To get a feel for what it is like to use the job system when there isn't
an appropriate job type take a look at

  https://dev.launchpad.net/Foundations/JobSystem

All that copy and paste code gets you to the point where you have a job
type (like BranchJob), and an implementation of a single job of that
type.

It's missing things such as writing the cronjob and getting it deployed,
and writing a UI to start/monitor/cancel etc. jobs of that type.

Thanks,
