If a connection gets send blocked for long enough (i.e. the peer application isn't draining the data right now, and thus not giving more flow control credit) the idle timer will fire. This is because no data is being sent over the wire while the sender is blocked. To me, it seems that we shouldn't consider a connection as idle if the application is actively trying to send.

While in this blocked state, should the transport periodically send some ACK eliciting packet to keep the connection alive?
