My original patch had two problems in syncache that broke IPv6
independently. The first was a C error where I missed a 'else'
in the #ifdef IPv6 mess and the second got the offset for the
IPv6 checksum calculation wrong because I missed to adjust it
to the new realities. Tor's quickly diagnosed the problem and
sent a patch which, due to some scheduling mismatch, I committed
only with delay. I'm sorry for the extended breakage period this
I thought I had tested IPv6 as well but as it turns out I have
changed /etc/hosts to use IPv4 first instead of IPv6 as is the
default. We should think of doing this in -current for 7.0 as
well. IPv6 is quite a bit slower than IPv4 still and everything
that uses localhost is affected by it.
