I hadn't noticed he switched the patch from newmems -> effective_mems.

This needs to be changed back to newmems, otherwise we're depending on
a derivative value set somewhere else in the code being correct instead
of using what we *know* is correct *at the moment we need to use it*.

So yes, go back to using newmems.
