Sounds good, thanks for confirming it.

Let me sleep on it wrt the "too many" QOS, or think if I should ditch this idea.

If I'll implement it, I'll post in this conversation details on how I did it.

Cheers

Yes, that's correct.
I guess you could create a bunch of QOS with different
PremptExemptTimes and then let the user select one (or indeed select
it from lua) but as far as I know, there is no way to set arbitrary
per-job values.

Best,
