I once worked on something where HZ=8000 was needed.

With HZ=8000, tick counts go negative after about 3.1 days.
"avoiding...longer than a day" is still safe, but has uncomfortably
small margin.  It might be wise to limit it based on ticks, rather than
based on time-to-sleep, using multiple successive timeouts if the wait
time is longer than (say) 1<<30 ticks....
