Why? I worked with a number of operating systems before encountering unix, and I've seen a few since. The setup and tear-down work involved with launching processes was a massive overhead that slowed things down and added very little value. Fork-exec, on the other hand, is quick because the child process inherits the environment, which has many other advantages - security, for example, is resolved at login and then inherited, similarly with I/O.
What's your objection to it? What dispatching system works better?
What particular principles of software design does the mechanism violate?
