When implementing this stuff, I could have merely made it possible for
exceptions to be new-style, and left the builtin exceptions as classic
classes. This didn't seem to be an especially good idea, as it would
leave code working _most_ of the time, only to break horribly when
confronted with a rare new-style exception. So I made the decision
(and I don't think I ever got around to explicitly discussing this
with anyone, nor if the people who actually updated my patch and
checked it in thought about it at all) to make the built in exceptions
new-style, precisely to make it a screamingly obvious change. I
didn't _know_ when I was doing it that I'd break Twisted unit tests,
but I was hardly a surprise.
I think the idea of a buildbot running various projects tests suites
with svn HEAD is a great idea -- back when I was doing 2.2.1 I did run
a few third party test suites (zodb comes to mind) but as always with
these things, automation is a good idea.
Cheers,

After long experiment it was found preferable to talking about why
Lisp is slower than C++...
