[Mauiusers] Standing Reservation Buffer

Hi,

I'm trying to set up a standing reservation as a buffer between two
queues. The idea is this:

There is a long job queue and a short job queue. I would like to have a
standing reservation have a higher priority than the long jobs, but
lower priority than the short jobs, such that it always keeps some nodes
free for the running of short jobs. The problem I have now is making
short jobs preempt the standing reservation. Once the SR gets a node, it
doesn't let go.

current configuration:

CLASSCFG[fast]      PRIORITY=75
CLASSCFG[long]      PRIORITY=25

SRCFG[reserved] PERIOD=DAY PRIORITY=50 STARTTIME=9:00:00 
SRCFG[reserved] ENDTIME=19:00:00 DAYS=MON,TUE,WED,THU,FRI
SRCFG[reserved] TASKCOUNT=5 FLAGS=PREEMPTEE FLAGS=SPACEFLEX

Anyone knows what's missing?
