Description

We should have the following tests:

• Basic priority test: submit jobs with different priorities and verify their proper ordering and running.
• New jobs with higher priority are submitted: verify that they are inserted at right positions in the queue and that they run accordingly.
• Changing the priority of an existing waiting job: verify that the order of jobs is rehashed.
• Changing the priority of an existing running job: verify that the order of jobs is rehashed and that running of the jobs is affected.
