That requires PEP 344. I have some vague feeling that the way we build
up the traceback by linking backwards, this may not necessarily work
right. I guess somebody has to try to implement PEP 344 in order to
find out.

(In fact, I think trying to implement PEP 344 would be an *excellent*
way to validate it.)
