> Note the ERROR a few lines from the end.
> This makes the server end see a transport-error (as the socket was abruptly
> disconnected) which seems like an error. Although a well written server
> should not really care about this anyway as it has already shut down the
> connection from its pov.
> Arguably there should be no transport-error in this circumstance at the
> server end. But it would definitely be better behaved if the client correctly
> closed the connection from its end.
