For now we receive the whole (E)TP in kernel and dump the whole message into all matching sockets. So it doesn't make any difference here. We were also having incremental recv() in the back of our heads, it's probably easier with only one socket. However it probably only makes sense on connect()ed sockets, as an ongoing huge ETP will block every small packet. And huge ETP transfers can take up to an hour...
