If user throttles receive by setting recv_mbuf_limit, after the net interface reports connection as closed we must wait for data to trickle through before disposing of it. There can still b data in the buffers (e.g. SSL). CL: mg: Ensure that user sees all the data before connection is closed PUBLISHED_FROM=22be0fa368950a9fdb03cfb00febc7c0a1674b01
