The proposed patch introduces new private function which chains previously fetched and current exceptions. This will help in correct implementing at C level an equivalent of following Python idioms:

    try:
        ...
    finally:
        ...

and

    try:
        ...
    except:
        ...
        raise

Sorry. Here is it.

I added 3.4 because this private function makes cleaner and more bug-free existing code (mostly recently added) and possible future bug fixes. Note a bug just fixed by Benjamin (changeset 888fd1cdec6f).
