This looks good, I would also like to add a step that can be done in
parallel: 

- Have the Cocoa port reviewed so that there are less questions about
  what it does and how it does stuff when it is included. Probably the
  changes to the common code are the most important.

Is the Cocoa port a complete replacement for the Carbon port from the
_user_ point of view? Does it support the same machines equally well?
If yes, then there seems to be little point in having both in the
tree, it might be better to remove the (already non-functional) Carbon
port as early as possible (now?).

Besides reducing complexity, it seems that there are not that many
people willing to work on the Mac platform, so having to deal with
less code might be a good idea.
