One more thought - perhaps this could be done after ipython works on
python 3? Then, the 2.x codebase could be left as-is, and the code in
py3 would be too (in the initial phase). But after a while, some
refactorings for the py3 version could start trickling in. This way,
2.x would be the "same old" python, whereas the py3 branch can
tolerate quite a bit of heavier breakage (because people are not
relying on its apis yet).

python 3 is a rather important project for ipython, since the
interactive prompt is where the users will be testing the py3 waters
first (and are probably less worried about having to jump a few hoops
to cater for IPython).
