Both blocks (message sender block, message receiver block) are source
blocks, both are directly connected to the inputs of a divider blocks,
i.e. the message receiver block is not at the downstream of the message
sender block. I guess this is ok because Message Passing is for
downstream blocks to communicate to upstream blocks. Is this correct?
The message passing API doesn't really care about who's upstream for the
streaming API.
This is part of the top_block.py generated by GRC, to illustrate the
flowgraph.

There's no msg_connect() call here -- that would be your problem.
