 2) is actually bug in you code. You supply &change in each
 call to kevent(), effectively re-introducing the kevent in each
 call.
 
 It should be coded like this:
 
 EV_SET(...)
 nev =3D kevent(kq, &change, 1, NULL, 0, NULL);
 
 for(;;) {
 	nev =3D kevent(kq, NULL, 0, &event, 1, NULL);
 	...
 }
 
 I've just checked this and this does fix the problem when using ONESHOT
 (the kevent() call blocks on second invocation, i.e. the original
 kevent is no longer triggered).
 
 I'm still investigating 1) - I have to double check what the intended
 interface really is, to figure if it's a bug or feature.
