[issue46717] Raising exception multiple times leaks memory

[George Gensure]

New submission from George Gensure <ggensure at fb.com>:

Instantiating an exception and raising it multiple times causes 1 frame and 2 traceback objects to remain allocated for each raise. The attached example causes python to consume 8GB of ram after a few seconds of execution on Windows/Linux.
