see problems with my code that I didn't see before the checkin, but:
When a subtype .mro() fails, we need to reset the type whose __bases__
are being changed, too. Fix + test.
[ 635933 ] make some type attrs writable
Plus a couple of extra tests beyond what's up there.
It hasn't been as carefully reviewed as it perhaps should, so all readers
are encouraged, nay exhorted, to give this a close reading.
There are still a couple of oddities related to assigning to __name__,
but I intend to solicit python-dev's opinions on these.
messages about MRO conflicts. (The tweaks include correcting spelling
errors, some refactoring to get the name of classic classes, and a
style nit or two.)
long but the double is too big to fit in a long. Prevent that. This
closes some recent bug or patch on SF, but SF is down now so I can't
say which.

Py_Init crash". refchain cannot be cleared because objects can live across
Py_Finalize() and Py_Initialize() if they are kept alive by circular
references.

style.
This raises TypeError for MRO order disagreements, which is an
improvement (previously these went undetected) but also a degradation:
what if the order disagreement doesn't affect any method lookups?
I don't think I care.
When mwh added extended slicing, strings and unicode became mappings.
Thus, dict was set which prevented an error when doing:
newstr = 'format without a percent' % string_value
This fix raises an exception again when there are no formats
and % with a string value.

slightly fiddled to catch more cases of list mutation. The dreaded
internal "immutable list type" is gone! OTOH, if you look at a list
*while* it's being sorted now, it will appear to be empty. Better
than a core dump.

angered some God somewhere. After noticing

I found that my cute test for the slice being empty failed due to
overflow. Fixed, and added simple test (not the above!).
classes was called with three arguments. This makes no sense, there's
no way to pass in the "modulo" 3rd argument as for __pow__, and
classic classes don't do this. [SF bug 620179]
I don't want to backport this to 2.2.2, because it could break
existing code that has developed a work-around. Code in 2.2.2 that
wants to use __ipow__ and wants to be forward compatible with 2.3
should be written like this:
def __ipow__(self, exponent, modulo=None):
