Thinking about it some more: for v6, I wouldn't use a packetized pipe at
all (due to the unnecessary extra buffer consumption.)  Instead just put
the message size in the header and read a large chunk, which may end up
being more than one packet and may end up with a partial packet at the
end.  *This is okay*, because there is only one reader, and any
additional data needed will be gotten the next time around the loop.
