This is fixed in [1505883e4a18b50e] and [cbeb34c75f0f49c7]. We now detect an EOF
due to close_notify from the peer via the SSL_ERROR_ZERO_RETURN status. We also
now send the close_notify as part SSL_shutdown in the TlsIO.c close function. So,
when the server closes the connection, the close_notify will be sent to the
client.
