Well, it turns out to be a bit big for attaching, so it's here:

http://starship.python.net/crew/mwh/hacks/new-style-exceptions-hacking.diff This is very much a first cut; no attempt at subtlety. The procedure went roughly "Hack until it compiles, hack until it doesn't dump core immediately, hack until most tests pass." The good news: all tests but testpickletools pass (and that's doomed; just look at it). Eh? testpickletools is a three-line test, which just runs the doctests in pickletools.py. The only exceptions mentioned in the latter are the builtin ValueError and OverflowError. What's the problem?

Sorry, was too obscure. One of the doctests pickles a couple instances of PicklingError and disassembles the pickle. That's not going to stay the same past an old-style/new-style transition.

Cheers, mwh
