Currently, for every rendering request (to render 128 samples) from the audio output unit, RemoteAudioDestination::render() sends an IPC message RemoteAudioDestinationProxy::RequestBuffer to RemoteAudioDestinationProxy in the Web process. That is unnecessary and inefficient. Since RemoteAudioDestination and RemoteAudioDestinationProxy use a ring buffer to transfer audio samples, we can "combine" multiple rendering requests in one IPC message. Hopefully, that will significantly reduce the number of IPC messages.
