You don't need the "with_traceback". Just "raise exc_info[1]". The original
traceback is already attached to the exception instance (major difference from
Python 2).

Oh and by the way:

    headers_set = []
    headers_sent = []

This is really a recipe for disaster. Please give these two variables clearly
distinct names. Your example is very confusing to read because of this.

Regards

Antoine.
