     It is normal/OK in the sense that it is implemented this way
     since day one. Since the RPF interface does *not* change the
     (S,G) entry with the information spt-pending is indicating that
     this entry is willing to switch once there is really a different
     RPF interface and this why we save state. It is not causing
     interop. problems and it is not against the RFC...

     Since you know now what it means it should not be irritating
     anymore ;-)
