You'd risk having jobs continuously preempted by jobs that have been in
queue for a bit: once a job starts, it stops accumulating priority ->
another job preempts the first, sending it back in queue -> the first
job accumulates some more priority and preempts the second -> loop !

IIUC, you can already do that. See TRESBillingWeights option: just set
the CPU and RAM to a low value relative to TRES/gpu.
