Preempt the specified running jobs.


vnc: Usage Message
  
  NC PREEMPT:
      Preempt the specified running jobs.
      Preemption means that:
      1.  The job is stopped or suspended (depending on method and age)
      2.  The resources of the job are revoked
      3.  If needed, a 'resumer job' is scheduled to
      restart the job as soon as the revoked
      resources are again available.
  
      If a job is not running, an error is reported.
  
  USAGE:
      % nc preempt [OPTIONS] <jobId> ...
