There are actually two bugs -- the mDNS bug that you described and the
fact that ping is doing a DNS lookup before sending each packet. I don't
know of another operating system that does this. Usually they do one
lookup before pinging, then none while pinging. Doing a ping before every
packet is my mind is just silly.
