I think you will hit all sorts of limits on the way if you do this,
not just the sunrpc locks. Using a single TCP connection means you
will have to serialize all sendmsg() calls across all clients, because
otherwise you'll mess up the RPC record framing.
You may also run into the max send/recv buffer sizes of a socket.
I cannot see how this can scale very well.
