+1!
I used to dislike this because there are use cases for letting the
exception survive the except clause, but I think I can get used to it,
and it seems the most straightforward solution of all that I've seen.
We could completely get rid of sys.exc_info()! I think we have a
winner here.
Explicitly created cycles are no big deal IMO -- these are no worse
than current code that explicitly stores sys.exc_info()[2].
