When endSync() returns -1 after buffered writes, a follow-up end() should stay pending until the readable side drains the queued data. Do not make duplex channel close() wait for that drain, since close() only needs to signal EOF to the peer. Waiting there can deadlock when the peer starts reading only after close() resolves.
