Re: libprocess: ordered message delivery

[haosdent]

As I know, Akka could guaranteed message ordering for per sender-receiver
pair, but not guaranteed message delivery. Erlang also similar to this. I
think if to implement own sequencing, acking, and retransmission logic,
this work nearly to reimplement a TCP stack. To implement a new TCP-like
stack in TCP looks strange. How about just make sure only have one
connection between per sender-receiver pair, so TCP could help us
guaranteed message order.
