Tom,


Regarding your latest-greatest state transition map:

Are you really sure this diagram is accurate?


Say, for example, a job is in the "held" state.  An operator or user then
cancels the job.  According to your diagram, the job transits would then
manner:


        held -> pending
     pending -> processing
  processing -> canceled


The same kind of mess occurs with the "processing-stopped" state, etc.


This certainly must not be what you intend, right?
