On the other side, timerfd(), socketfd() and epoll() are all there to do a single thing. FreeBSD did the retarded thing when they reimplemented sendfile() roughly a week after Linux added it. TCP_CORK is still not implemented in FreeBSD. mremap() was NAKd, there's the whole MMAP_ANON vs. MMAP_ANONYMOUS, or the weird bits of mmap in general.
Cooperation is much more like to happen in the FreeBSD => Linux direction, IMO ... but that could also just be the much bigger developer pool.

epoll <=> kqueue is probably the best case test too, to be convincing you'd want something that benchmarked EVFILT_VNODE/SIGNAL/TIMER at least. To be really convincing you'd want PROC/USER/AIO and play with the EV_* flags.
