Oh, I agree.

And I think something like CLONE_EVENTS would be fine - and decide
yourself what kind of threads you want (do you want indistinguishable
"anonymous" threads like apache, or do you want a threads that handle
separate event queues). Or you might have a mixture of the two - for web
serving the "accept()" event list might be a separate thing with a few
threads doing that, while "worker threads" handle the actual IO..

But if you want to have some event queue ID, I just wonder how you'd set
it up sanely without tons of complications..
