    kernel - Remove ad-hoc increment/decrement of vm->vm_sysref
    
    * Remove the ad-hoc increment/decrement of vm->vm_sysref when pulling data
      out for a ps.  Acquire p->p_token instead.
    
      This is an attempt to determine whether these adhoc operations are
      responsible for causing a race that results in the seg-fault issue we
      see on monster.
