There is no "global" message queue in the context of cells.

Again, there's no single message queue in the context of cells.  I'm
assuming that was to avoid a bottleneck, but Chris Behrens would be able

this discussion is trying to address one element of the current design;
I'm not trying to redesign cell communication.
