Created attachment 859822 [details]
this fix works for me

Description of problem:
in case of e.g. broken firewall rules, ping does not pause when getting error (e.g. Destination Host Unreachable)

Version-Release number of selected component (if applicable):
20121221-4.fc20

How reproducible:
100%

Steps to Reproduce:
1. iptables -I OUTPUT -o eno1 -p icmp -j REJECT --reject-with icmp-host-unreachable
2. ping 24.24.24.24
3.

Actual results:
From 192.168.1.103 icmp_seq=1 Destination Host Unreachable
repeating as fast as possible

Expected results:
little delay between packets, at least when not using -c option
