In practice it is unlikely that data that's too big for the reliability layer won't need splitting
anyway by the application at some point, and the libraries are already too open to OOM DoS.
The previous testcase was "all nodes communicating randomly", basically a worst-case.
This testcase is somewhat more realistic, a set of nodes communicating between each other via other
nodes, a given TO node recurring once every 5 seconds (approximately).
Notably, the 'packet transfer total' figure should be halved, as in the testcase pings and responses
are used, but only responses are counted.
