New Autotuning

(Paper in progress)

Reformulate socket memory model
Socket buffer isolates the application from the network
No per connection limits on Retransmit & Reassembly queues

Announced Rwin is twice the data from prior RTT
this is the flow control baseline
receiver side RTT estimate might be weak

Global controls on total memory to prevent deadlock

Detect and penalize misbehaving connections
E.g. not honoring Rwin
