Evgeniy, i'm not sure how many different ways to tell this to you, but
you are not listening, you are not learning and you are still not
getting it at all.

The scheduler /IS/ a generic work/event queue. And it's pretty damn
fast. No amount of badmouthing will change that basic fact. Not exactly
as fast as a special-purpose queueing system (for all the reasons i
outlined to you, and which you ignored), but it gets pretty damn close
even for the web workload /you/ identified, and offers a user-space
programming model that is about 1000 times more useful than
state-machines.
