Optimize transport some more

Browse source 
We can optimize the transport some more if we allow the host to
configure the area used for transfering buffers. We can then also place
the current status in the area and avoid calling get_status(). We can
also allocate this area in shared memory, avoiding a memcpy in the
client-node.
