* - it needs reset_job_bitmaps() in order to rebuild node_bitmap fields,
* - it relies on _sync_nodes_to_jobs() to
* o kill active jobs on nodes now marked DOWN,
* o reset node state to ALLOCATED if it has been marked IDLE here (which is
* an error case, since there is no longer an ALPS reservation for the job,
