    usr.bin/netstat      route.c 
  Log:
  Make netstat -rn more resilient to having the routing table change out from
  under it while running.  Note that this is still not perfect:
  - Try to do something intelligent if kvm_read() fails to read a routing
    table structure such as an rtentry, radix_node, or ifnet.
  - Don't follow left and right node pointers in radix_nodes unless
    RNF_ACTIVE is set in rn_flags.  This avoids walking through freed
    radix_nodes.
