it's doubly odd, because there's no reason for an interrupted writer to go
to the lengths of writing an empty record as a consequence of being
interrupted. it will waserror out in the writer, so why should an empty
Block end up on the underlying Queue?
In fact, an interrupted writer in devmnt will start the flush(5) protocol,
so it will be writing Tflush, not empty records.
