When two people edit the same job configuration, they will overwrite each others changes.

Let's say I open the Configure page of a job, then go to lunch. In the mean time, somebody else edits that job. When I come back, I change a minor detail and click Save. The changes of the other person are lost.

Expected: At least a warning message or anything, that somebody else was editing the job.

Workaround: I have made it a habit of reloading the Configure page immediately before I make a change and click Save. I doubt anybody else does something like that, though.
