There are still too many boxes out there that drop the main packet
when doing an ARP. This hurts UDP stuff more than TCP flows.

Some of us are (unfortunately) behind some major US providers which
experience as much as a 50% packet loss rate on bad days and 20% and
above is quite common.

Now, if TCP/IP engines would do Path MTU discovery and quit sending
those little 500+ byte packets whenever something goes off their
subnet...
