Research direction

Start with pty.py and the test_pty.py coverage referenced in the uploaded patches; reproduce the pty.spawn hang after the netcat client disconnects. Review the existing pty.patch and test_pty_and_doc.patch, then confirm that the test cases pass without regressing behavior on supported Unix systems.
