Diff to fix traceroute6

If traceroute6 is run and one of the hops is not responding, receipt of an =
IPv6
ICMP echo reply will cause traceroute6 to re-execute the wait on the current
probe. If echo replies are coming in at a rate faster than the timeout,
traceroute6 will essentially wait forever on the non responding hop.

This can be easily reproduced using ping6 and traceroute6 simultaneously in=
 the
presence of non responsive hops.

A diff which corrects the problem is attached.
