I'd assigned this to myself since I was discussing it with Brandon when he was working on it at the PyCon sprints. Since I certainly don't want to block anyone else getting to it, I'm unassigning it - feel free to take it forward :)

IIRC, the copy.py changes were things Brandon and I discussed at the sprints as cases where they were legacy code that was no longer needed in Py3k, so it made more sense to just delete them rather than add tests to cover them. Definitely makes sense to split those changes out into a separate patch, though (easier to revert if we later discover the code isn't as useless as we think it is).
