Given that traceback printing isn't a performance-critical activity, there 
probably isn't a reason any more for requiring a particular C layout.  On 
the other hand, being able to create frame or traceback instances or 
subclasses would probably also solve your problem, without having to do too 
much hacking on the C code that expects a particular layout.
