I can't recall specifics but I had a working routing daemon skeleton
using UDP with kqueue around 5 years ago.
I didn't use oneshot, and treated it much like select() i.e. the input
event is level triggered, every time you call you should get the event.
This is unlike WSAEventSelect() in Windows which is edge triggered.
