 *  Fix: Don't crash if the connection is closed when sending a degraded ping. This fixes a
    regression that was introduced in OkHttp 3.14.5.

The application-layer can also do blocking reads. If the application asks to read and there's nothing available, we need to hold that thread until either the bytes arrive, the stream is closed, or a timeout elapses. If we get bytes but there's nobody asking for them, we buffer them. We don't consider bytes as delivered for flow control until they're consumed by the application.
