Some attacks are effective not only user client but also keyserver.
If keyserver found duplicate key then return "Found duplicate
key". It's OK. It's little cost.  If keyserver found duplicate key
then return all of key contents.  It is a possibility of DoS not only
user client but also keyserver. v3 is problem but we have to support.
