Of course it adds overhead. The alternative is a monolithic system
without clearly defined and separated subsystems. That would suck.
There would be only one kind of Kernel, and only one sort of Session,
and only one object layer. They would all be inextricably intertwined
and a huge mess to maintain.
Your corollary is false. Poe events are a low level transport for
high level object messages.
