The case that I was wondering about is the common case where 
getsockopt(SO_ERROR) succeeds and I was wondering if the code should 
actually be:

if (sockopt_arg != 0 ) {
   errno = sockopt_arg;
return -1;
}

That way the caller of NET_Connect will have errno set so that 
XXX_ThrowByNameWithLastError can create an appropriate exception message.
