K 10 svn:author V 7 iedowse K 8 svn:date V 27 2004-02-08T21:59:17.000000Z K 7 svn:log V 410 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. PR: bin/4696 MFC after: 1 week END
