This is a common assertion but it is factually incorrect with respect
to TCP.  

If the 3rd packet of the 3-way handshake is lost, *and* the
application protocol is one in which the server is the first to send
data (e.g., a connection banner), the client will move the connection
to ESTABLISHED state and quietly hang waiting for data to arrive,
while the server will have no record of the connection....

The SYN-ACK must be retransmitted if not acked.
