How can I do an orderly vs a disorder TCP disconnect using CFWriteStream in my daemon? If I CFWriteStreamClose() immediately after my last CFWriteStreamWrite(), the data may or may not get sent out.

From the documentation, I gather that CFWriteStream buffers data internally before actually sending it down the wire, and I can query it if I can add data to the buffer, but there doesn't seem to be a way to query if that write buffer is empty, or to flush the buffer before closing the stream.
