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.

little Alice and all her wonderful Adventures, till she too began
dreaming after a fashion, and this was her dream:--

  First, she dreamed of little Alice herself, and once again the
tiny hands were clasped upon her knee, and the bright eager eyes
were looking up into hers--she could hear the very tones of her
voice, and see that queer little toss of her head to keep back
the wandering hair that WOULD always get into her eyes--and

* Kubelets using TLS bootstrapping (`--bootstrap-kubeconfig`) or certificate rotation (`--rotate-certificates`) store certificates in the directory specified by `--cert-dir`. The default location (`/var/run/kubernetes`) is automatically erased on reboot on some platforms, which can prevent the kubelet from authenticating to the API server after a reboot. Specifying a non-transient location, such as `--cert-dir=/var/lib/kubelet/pki`, is recommended.
