> SimpleClient uses a CQLMessageHandler instance to deal with response messages
> in the V5 framing format. It looks like CASSANDRA-16663 broke SimpleClient's
> ability to return capacity allocated during the processing of inbound
> messages (i.e. responses from server->client) back to the global and
> per-endpoint resource monitors. The change in behaviour introduced in
> CASSANDRA-20052, in which we now push back to the client when a capacity for
> a large message can't be allocated, causes SimpleClientPerfTest in the burn
> suite to fail on V5/V6. This is purely because the test expects the client to
> run for a fixed period without interruption, but now it halts as soon as
> capacity is exhausted. The simple fix is to restore SimpleClient's capacity
> return.
