Really high-performance server applications will generally prefer cooperative multi-(task|thread)ing.

That statement is indefensibly broad and, in my experience, incorrect. First, I don't know of a single system which uses cooperative multi-threading (I would say there's never been one, but I'm no CS historian). In all the systems I've seen multi-threading is preemptive, not cooperative, for obvious reasons. Second "really high-performance server applications" come in so many different shapes and flavors that stating that any one technology will be "generally preferred" is just dumb.

For my "really high-performance server applications" I use a pool of pre-forked processes, and it works quite well! That doesn't mean it's right for all tasks but it does suggest that cooperative multi-tasking might not be the undisputed king of silver bullet land!
