Well in the old days, the operating system was there to help you. If plugins were standalone processes, they could be resource-constrained. But they all have to run in-process because of the LAMP architecture.
Hence -- cooperative multitasking.
I've been complaining about it for years. Eg: http://clubtroppo.com.au/2008/07/10/shared-hosting-is-doomed...

Thanks for the article, it's insightful and I & history agree completely with you. Nowadays, people are using prebuilt VPS images or automation scripts to provision their servers and shared hostings are becoming more of a VPS hostings with a good UI around these tools.
I see that you are a WordPress veteran, nice to hear your opinions :)
I see, happens all the time.

Yeah, it's just a matter of preference and convenience.

This is the real issue. I know a very few WordPress developers who have a formal technical education. While you can learn it yourself, school forces you to learn this in a great detail. In a near future, I will hopefully write on these topics, though, I need to study on this a bit more first.
