 // failures, there is no guarantee of orderings.

 // Jobs are grouped into two priority levels:
 //   - USER_INITIATED jobs are those occur as a result of direct user actions.
 //   - BACKGROUND jobs runs in response to state changes, server actions, etc.
 // USER_INITIATED jobs must be handled immediately, thus have higher priority.
 // BACKGROUND jobs run only after all USER_INITIATED jobs have run.
