I ran all my tests and see only the changes in tests related to the new pages.

So far as I can tell we only have to look for assignments to self._cellvalues etc etc in the splitrows method.

For whatever reason we have T is self in the non-splitInRow case so we have to be careful about assignments to T.attr in 
the code executed by that branch.

I think on the other branch we create a new T, but it's not clear that we are setting stuff back on self unless some 
mutable is shared and then modified.
