[no status change, this issue currently does NOT need any attention]

To keep issues separate, I just wanted to document a comment about this issue mentioned in issue29070. It refers to the _copy loop.

        if STDIN_FILENO in rfds:
             data = stdin_read(STDIN_FILENO)
             if not data:
                 fds.remove(STDIN_FILENO)
+                # Proposal for future behavior change: Signal EOF to
+                # slave if STDIN of master is gone. Solves issue29054.
+                # os.write(master_fd, b'\x04')
             else:
                 _writen(master_fd, data)
