Uh, really? If you want to suppress all reference cycles, you *have*
to remove __traceback__.
The problem is to make computation of the traceback summary
lightweight enough that it doesn't degrade performance in the common
case where you don't have to print the traceback later.
So why can't we allow instantiation of types.TracebackType &
types.FrameType?
It should be about the same time to reconstruct traceback and
its frames without locals, as to create named tuples.
