Ahh yes.

Buit couldn't DofMap::reinit() copy the send_list before distributing new dofs? 
 That is the list we want...

Whoa, wait, take a closer look at my patch.  There's two localize
calls it was supposed to fix.  In the second call, it *uses* the
DofMap send_list, because we're synchronizing data on the new, current
partition.

But in the first call, it *can't* use the DofMap send_list, because
where data needs to come from and needs to go ends up having nothing
to do with either the old partitioning's ghost nodes or the new
partitioning's ghost nodes - it has to do with how the old partitions
and new partitions overlap, and to the best of my knowledge we've
never constructed a send_list like that before.
