	    NXFreeObjectBuffer(buffer, length);
	    return returnValue;

This writes out a graph of the object and then reads it back in, all in memory.

Thanks, this is a nice way to copy an object.  (Looks like NeXT punted on
the -deepCopy method in class Object?)

However, it seems that it does not preserve the outlet connections that
have been set up in the interface builder.

P.S. Thanks to everybody who pointed me to Example 4 in the Interface
Builder chapter of the 1.0 manual.
