This is silly. The server sends the alert on a best-effort basis.
We cannot impose a magical requirement that the alert gets there.
The requirement is to send, not to guarantee successful transmission.
Sending is easy, just write the alert down the socket (even that
might fail and that's fine).
In practice, if the the server is the first to detect an error,
its alert gets to the client. There's no need to read too much
into this.
