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  The sockets and corresponding file descriptors are no 
longer valid.
