Don’t connect sources and sinks directly, use a pipeline to move data around.

- * A connection reads bytes from a {@link Source} and feeds it to a sink. This
- * class is meant to be subclassed by each {@link Sink}, overriding the {@link
- * #feed(byte[])} method to actually feed the data into the sink. The {@link
- * #feed(byte[])} method is also responsible for blocking for an appropriate
- * amount of time; this method determines how fast a {@link Source} is
- * consumed.
