Am I doing something wrong - or do we really not have a specialization of
Communciator::allgather() for std::vector ?
I know that broadcast is implemented (because I'm using it in another part
of the code). But I'm seeing this when I try to do allgather():

You're right - it doesn't... I misread my old code... I missed my own
packing/unpacking of the coordinates from/to Points (read them out into a
flat array, broadcast(), recreate Points).
So - never mind. I guess I'll do the same thing again for now.
How tough would it be to make this work with P
