[GE users] priorities (for array jobs)

Two questions (SGEEE v5.3p6)

- Users can't submit jobs with positive priority values or qalter pending jobs 
to higher priorities.  qsub -p 1 is silently ignored and the job gets priority 
0.  qalter -p 1 yields 'denied: "user" must be operator to increase job 
priority'.  Is there a way to enable all users to set positive priorities 
without giving them other operator privileges?

- Each host has a queue for normal jobs and a queue for urgent jobs.  The 
urgent queues offer a resource prec=1 while the normal queues offer prec=0. 
When all the normal queues are full and I submit some more jobs that request 
prec=0, followed by some jobs that request prec=1 (same priority for all), my 
urgent (prec=1) jobs wait behind my normal jobs, even though they could be 
dispatched.  Shouldn't the scheduler detect this and allow my urgent jobs to 
run, even though they were submitted after my normal jobs?
