What is the latest consensus on the so called C10K problem?

Merged with Is there any modern review of solutions to the 10000 client/sec problem.

This is probably a well known discussion: http://www.kegel.com/c10k.html

Although it's been updated in so开发者_C百科me places on the page, I'm wondering if there is a newer and more clearly articulated consensus or distilled wisdom on this challenge, with regards to the latest state of the operating systems and the available libraries?
