--------------------------------------------------------------------------
The failure can be reproduced more reliably by adding a delay into
org.apache.cassandra.transport.SimpleClient.SimpleFlusher#writeLargeMessage
logic between sending of subsequent frames of a large auth message. so we have
one of two cases:
* (normal case) client is fast enough to send both frames into an open TCP
socket before a server logic starts to process - in this case we see the
expected Protocol error on a client side
* (flaky case) a server processed the first frame before a client have sent the
second one, the server closes the connection after the first frame processing,
so a client gets another error when it tries to send the second frame.
