[torqueusers] Cpusets and qrun

We run 2.5.8 with cpusets enabled. When jobs with large memory requests
(which does not allow to fill all virtual processors) are launched on a
node the jobs are bound to the lower core numbers. This does not play
well with the NUMA architecture.
Is there a way to specify the virtual processor the job should run on
when using the qrun command?
