The point is that apart from the single special case of writing to the screen, every I/O (including reading from the mouse or keyboard) involves messages. And the screen output stuff also involves massive amounts of shared data. Which UNIX doesn't bother the program with. It's a fundamental difference in O/S philosophy. And it makes resource tracking on the Amiga a much more complex problem.
