I've sent an updated patch with the fix that Sarah mentioned. I 
also added "core updates" to the PATCH bit, because I imagine 
Sarah is right that this would trigger a bunch of rebuilds.

I'm not sure that these changes warranted a two year wait on this 
patch, but I still think the patch is worth merging.
