But I thought exactly *that* is what reservations were meant to *solve*.
That free resources get reserved for a job A, asking for a reservation,
so that other jobs with lower priority which *wouldn't end* before job A
- because of s_rt and/or default_duration settings - don't get started
on that *reserved* resources.
Isn't this the way resource reservation is supposed to work?
Or is the mixing of different PEs the culprit of me not understanding it?
