Regardless of whether those complicate the kernel - and I suspect
khttpd and tux don't complicate the kernel much - what Linus
is doing here is different: he's doing a reductionist analysis
of what it takes to do poll() right.
I've done the same thing before, and yes, the people whose favorite
interface I seemed to be ignoring were pissed off. But it was the
only way for me to understand the true requirements. In the end,
I usually add back part of the stuff I initially stripped out,
once I understood what it was for.
That said, I like kqueue, and I don't like the interface Linus proposed.
But I'm still not quite sure how to demonstrate that
his interface won't do the job. (Wish I had time.)
