I see explicit machinery in the implementation of chare arrays to
ensure that all broadcasts are reflected off of a 'serializer' PE,
putting their transmission from that PE in a particular order.
However, I can't find what guarantees that all PEs receive the
broadcasts (CkArray::recvBroadcast()) in that same order.

Given that the array implementation assumes ordered receipt of
broadcasts and numbers them locally for delivery to array elements, I
figure that means that the group-level broadcasts must happen in
order. Can someone please point me to where that order is imposed or
enforced?

Thanks,

Phil
