Well, msleep() is in terms of milliseconds while schedule_timeout() is in terms
of jiffies. Thus, you would use HZ if you called schedule_timeout() [and
it would always sleep (at most) one second, because HZ counts the number
of jiffies in one second] and you would use 1000 if you called msleep()
[and it would always sleep (at least) one second, because there are 1000
milliseconds in 1 second].
