Actually, I've never used FreeBSD, so no.
Thanks for the long answer. But I don't get where hz comes from. It's
obviously not timer <not 0> then. (And 18.2 Hz might be a bit slow.)
So is the "hz tick" just another event that timer 0 checks (and sets up
an interval) for then?
(And is then timer <not 0> used to calculate how many cycles there are to
go until the next tick? (Since timer 0 is "unsuitable for keeping track
of ''real'' time") )
This stuff is interesting, had to think for a bit too. Thanks again.
