Don't mess around with non-blocking.  Even recv(8000) will return
more or less immediately if you send any data at all, so it seems
kind of likely you're sending no data until the CR.  Substitute a
test client that has its data built in, and just send('i') to the
server.  I bet recv() will get it right away, Nagel algorithms
notwithstanding.
