we're assuming hz=1000 and not gracefully handling when it isn't. The math involved will return 0 for hz < 1000, which it is on some platforms and on DragonflyBSD. This doesn't fix it, it: * converts one manual use over to use the macro, and * comments where it needs some thought/fixing. I'll think about this a bit more before fixing it.
