Even though TWSocket.Close also calls ShutDown(1) it actually
does not perform a bidirectional gracefull shutdown, since the
socket handle may be closed too early. In order to initiate a
gracefull shutdown after the last byte has been sent call
shutdown(1) from event OnDataSent.
For example, SendStr('bye bye') followed by a call to close()
does not ensure the string is received at the peer.
