  Log:
  Certain ICMP error replies cause ping to perform a reverse DNS
  lookup on an IP address from the packet (such as the IP that sent
  a TTL exceeded error). If the DNS lookup takes a long time, ^C will
  appear to be ineffective since the SIGINT handler just sets a flag
  and returns. Work around this by exiting immediately on receipt of
  a second SIGINT when DNS lookups are enabled.
