Work on better scheduling

Also use double buffering for the client-node input, we process the
output of the previous cycle.
Only process the reuse_buffer if the client is explicitly going to
send them otherwise, recycle right after sending.
Let the tee and mix pass the io status upstream.
Initialize io area with NEED_BUFFER for inputs.
Implement reuse_buffer for the remote.
