I think that I understand the reasons for having 3 URLs returned, but
I still keep thinking that 1 job URL would be better and simpler.  

Harry's example above reminds me of this problem when he mentions that
the list of jobs returned should include at least two job URLs for each job
(i.e. the query url and the modify url).

We may also decide to add more URLs later and have different URLs for
cancel and for modify, giving us 4 job urls.

Does anyone else think that we should strive for one job URL, and have
the operation specified in the message, or am I alone?
