"queuewise premption counts preempted job + preempting job as 1 slot

For example, rqs 'hosts {*} to slots=$num_proc' will allow jobs to 
run in the subordinate queue and in the superordinate queue."

This was always counting as 2 slots for me (just tested in 6.2u5), but you may notice the limit later.

What you can do in your case anyway, is to define two RQS which are limited to a queue each:

limit queues sub.q hosts {*} to slots=$num_proc

and in another RQS:

limit queues sup.q hosts {*} to slots=$num_proc

On a host level this isn't working of course, as you pointed out.
