Python 3.4 introduced frame.clear(), but frame.clear() raises an RuntimeError if the frame is still running. And it doesn't break all reference cycles. An obvious workaround is to store the traceback as text, but this operation is "expensive" especially if the traceback is only needed in rare cases.
Another "obvious" workaround is to call frame.clear() from the parent function (i.e. have a dedicated wrapping layer).

Antoine.
