Log Message:
Found and fixed an interesting issue with automatic metaclass generation
and class advice.  My algorithm for determining the "best" metaclass was
broken in some way.  I no longer understood the original algorithm, so I
rewrote it from first principles, and added a test to cover the way the old
one was broken.  It's kind of weird that I never discovered it before, but
until recently its main use was just to automatically generate new
metaclasses.  So the bug would have just caused it to generate extra ones
that weren't needed, which of course wouldn't be directly noticeable.
