If EFF needs to perform a DNS query on each hostname it receives a
certificate for, EFF will leak information to an attacker watching its
servers.  If EFF tries to not log hostnames which do not exist, EFF
will leak a user's request time *every time* that it receives a
certificate associated with a non-existent hostname.
