Right; thanks especially for the questions about what confused
programmers who aren't used to dealing with half-closed states might do.
 Probably best to stop using "close" except for full close. And kill
closeForReceiving. Leaving better names and simpler specs:

interface Carriable<T> extends AutoCloseable {
    boolean isClosed();
    boolean isFinishedSending();    // closed or sending disabled
    //...
}
interface CarrierSender<T> extends Carriable<T> {
    void finishSending();           // disable sending; close when empty
    // ...
}
