Better explanation of jump-to-CFS optimization removal
GSN-EDF and friends rely on being called even if there is currently
no runnable real-time task on the runqueue for (at least) two reasons:
1) To initiate migrations. LITMUS^RT pull tasks for migrations; this requires
plugins to be called even if no task is currently present.
2) To maintain invariants when jobs block.
