yes, but RFC 826 was written in a time when arp poisoning attacks were not a
concern so, that argument is not relevant.

I thought that windows did not update its cache in this case but I don't have a
machine handy to verify that it is really the case.
Anyhow, I did not want to say that I was against this patch. I just meant to
explain why I think it was not done that way yet.
