   // HACK: yield if reader is called too often.
   // Problem is lack of synchronization between host and renderer. We cannot be
   // sure if renderer already filled the buffer, and due to all the plugins we
   // cannot change the API, so we yield if previous call was too recent.
   // Optimization: if renderer is "new" one that writes length of data we can
   // stop yielding the moment length is written -- not ideal solution,
   // but better than nothing.
