So, if I've understood correctly, the purpose of this patch is to
improve performance on a multi-CPU system, which has the kqueue()
function. Most notably, FreeBSD?

OS X also has this, so it might be worth trying on a multi-CPU Mac.

If there's no measurable difference in performance, between kqueue() and
poll(), I think we should forget about this.

I agree that we shouldn't add this unless it's demonstrably a win.
No opinion on whether your test is adequate.

I'm marking this as "Returned with Feedback", waiting for someone to post test results that show a positive performance benefit from this.
