I think the word code patch should go in sooner rather than later.  Several of us have been through the patch and it is in pretty good shape (some parts still need work though).  The earlier this goes in, the more time we'll have to shake out any unexpected secondary effects.

P.S. The patch is smaller, more tractable, and in better shape than the C version of OrderedDict was when it went in.
