You might want to look at the description for the finishUnarchiving
method (for example in Object).  This mechanism can allow a template
to return another object, sort of like:

	- finishUnarchiving
	{
	    Window * new_window;
	    new_window = [Window newContent...] // init from
		// template's instance variables
	    [self free];
	    return new_window;
        }

So if you had overridden the newContent... method, your self would
really be the "true" object and no copying needs to be involved.
Note, of course, the actual class to which the new method is sent
would not be hard-coded, but specified from information kept by
Interface Builder.
