[Mauiusers] reservations vs. standing reservations

I have a question about the interaction between standing reservations and
advance reservations (those set from the command line with setres).
I had set 40 nodes aside using setres for a particular user. That worked
well; the nodes eventually all were free and his 40-node job started and
In the mean time, I created a standing reservation for 16 nodes (with
property SPACEFLEX); aside from the 40 set aside for one user, there are
35 additional nodes from which the SR can choose.
When the users 40-node job ended, about 2 days into his 14-day
reservation, the SR grabbed 16 of his nodes and allocated them for itself.
This confused me.
I would have expected those 40 nodes to be "off-limits" for standing
spaceflex reservation or normal maui-created job reservations.
The down side of this is that the SR had started to gather nodes to get to
its needed 16; now it has relinquished those thinking it can use 16 of the
40 that were already set aside.
Am I misunderstanding something here? Or is there some logic in the code
that isn't quite right?
