Hard to say. If process P has a large mailbox, it is more expensive in
reductions to send a message to P. But I'm not sure this is what you are
seeing here. The guard against such things are to employ some kind of flow
control scheme between processes. Usually either credit-based flow or
window-based flow. Maybe the tracing interacts, I honestly do not know. We
are in read-the-source to understand anyway at this point.
