    kernel - close more kqueue MP races
    
    * Leave the KN_QUEUED flag set while processing a knote in kern_kevent().
      The flag prevents the knote from being requeued while blocked in the
      filter function.
    
      Document this requirement.
    
    * Use kq_token in a few more places
