If we make IPv6 non-conditional that should essentially fix this
problem, right?

No, libverto cannot emulate idle since it means something very different
than timeout of 0. This could have very bad effects for someone who asks
for idle and gets timeout instead (imagine 1000 idle events that should
be run gradually when there is nothing else to do, but are instead run
immediately, blocking processing of other requests).

In this case, timeout is acceptable since we just want to finish the
currently processing requests. But in general, timeout cannot emulate
idle.

I did not see either of these... Perhaps my grep-fu isn't as good as
yours?
