Correct - there is no "look ahead" feature in SGE - i.e. after the suspension
you would be inside the granted limit again. The suspension is the result of
another job in another queue being started. You can try:
limit queues !urgent.q hosts {*} to slots=$num_proc
with feasible limits inside the urgent.q. For a short time until the suspension
starts you allow an oversubscription (although it might be parts of a second
only).
