Eventpoll in Linux has exactly the same problem. For this reason
I added poll support to the /dev/epoll device itself.
By doing that I can have a smaller result with "weird" files on
which I actually call poll(). If readiness is indicated on the
eventpoll file descriptor I do a EP_POLL to get the actual
events.
Would it be possible to multiplex with kqueue in a similiar way ?

Even better.
