The https://www.rfc-editor.org/rfc/rfc1350, section 6, Normal Termination recommends not to close client connection immediately, but rather wait for a while, as the final ACK may be lost in the network.
In such case the client would re-transmit final DATA packet expecting server to send a final ACK again.
This is also fixing #5 when socket is closed too fast, effectively causing final ACK to be lost.
