Hello people,

This iteration of the series removes the START and END flags (and
hence the header associated with each buffer). That's the major change
since the last submission.

I think the biggest issue remaining is the buffering.

I think this is a pretty fundamental issue to work out since it determines the very nature of the transport (stream vs. datagram).

Because you have to put a max buffer size on the transport, I think buffering is a really flawed approach provably equivalent to just increasing the message size within the transport. In general, the later is a better approach because then the guest is using it's memory vs. using host memory.
