[torqueusers] pbsnodes reports the same job running many times

What is the qstat -f output for this job? pbs_server reports dedicated
resources in pbsnodes output, so if the job requests 4 execution slots and
runs one process, pbs_server will report 4 execution slots as occupied.
Conversely, if a job asks for one execution slot and uses 4, pbs_server
will not scale up what it reports.
