old_page_index is read and used above.
old_app_launch_index, on the other hand, is read but not used. 

Will this not change the order of apps, potentially?

[csharp, 2011/11/17 19:51:58]

I don't think the order can change, because set that we are iterating though
here is sorted so that when we are placing an app, all the ones before it have
already been placed, so we know it will go into the next open position.

This could break if we have positions that have no app, but are suppose to show
up as empty space in the NTP, but as far as I'm aware we don't have that.

Yes, which is an invalid ordinal which does represent an unset pref. I've added

Are there cases here where you can end up with {StringOrdinal(),
StringOrdinal()} ?

[csharp, 2011/11/17 19:51:58]

It is possible, but the map only updates for valid ordinals. If either input is
invalid it has no affect on the mapping (if the other value is valid it will
still affect the map by itself).
