FWIW: https://git.gnome.org/browse/glib/commit/?id=3904c8761a60dbadbdfaf98fe23ff19cbdcc4a9a Since that a lot of userspace (including NetworkManager) uses eventfd. I haven't tried this patchset myself but I'd look at what the GLib mainloop is doing.
eventfd really isn't the interesting piece, the interesting piece is epoll, especially if used in level triggered mode.
