I get the impression, from what little I known about threading, that it is
likely you are under estimating the complexity of the threading problem.
I get the feeling that *most* non-experts do (either that, or they just assume
it more complex than they want to deal with).

You are crazy! processes+IPC only works well if either the OS supports very
fast IPC (IIRC none do aside from shared memory and now we are back where
we started) or the processing between interaction is very long.
Everything is indicating that shared memory multi-threading is where it's
