There are some larger changes in the C API of Python 3.0 (e.g. objects
contain a structure containing type and ref count, rather than
directly embedding those members), but there are some compatibility
macros in Python 2.6.

I think it'd be possible to port these backward compatibility macros
back to at least Python 2.4, which would greatly reduce the amount of
code that needs changing for 3.0.

There will be some backward incompatible changes (especially in the
Python code level), so I'd recommend a separate branch for 3.0
development.  By keeping the delta between the 3.0 and 2.x branches
close, hopefully it'll be possible to merge fixes from one branch to
the other.
