--- Comment #1 from Warner Losh <imp@FreeBSD.org> ---
It used to be you needed to reduce the number of ticks by one to get the
desired behavior from callout. The exact value of quanta doesn't matter too
much since the result of this bug is systematic (and we take it into account
based on elapsed time). However, this makes the behavior more predictable.
