 *  New: `OkHttpClient.Builder.minWebSocketMessageToCompress()` configures a threshold for
    compressing outbound web socket messages. Configure this with 0L to always compress outbound
    messages and `Long.MAX_VALUE` to never compress outbound messages. The default is 1024L which
    compresses messages of size 1 KiB and larger. (Inbound messages are compressed or not based on
    the web socket server's configuration.)

      MockResponse.Builder()
        .setHeader("Content-Type", PLAIN)
        .body(Buffer().writeUtf8("Uncompressed"))

          .build(),
      ).execute()

    of unacknowledged data per stream and no per-connection limit.

 *  Fix: Don't close a `Deflater` while we're still using it to compress a web socket message. We
    had a severe bug where web sockets were closed on the wrong thread, which caused
    `NullPointerException` crashes in `Deflater`.
