Yes. Definitely lose the shutdowns. The close() function decrements the descriptor's reference count. The socket is really only terminated when the reference count goes to zero. Shutdown, on the other hand, will terminate the socket no matter what the reference count is.
In your case, shutdown causes the parent to terminate the child's socket and vice-versa. The sockets and corresponding file descriptors are no longer valid.
