I misread the the documentation, it is in fact possible to do a non-blocking 
poll using the aptly named EVLOOP_NONBLOCK flag :-)

I do think that implementing nio using libev is more work than just using 
kqueue directly, because the libev API is more complex. Especially 
considering the fact that I now have an almost correctly working kqueue 
backend here :D.
