Making a task have a longer period is "trivial." If I would want to extend
the period of a task by, say, a factor of four, I would only do useful work
every fourth time the task was entered. You'll waste a small amount of CPU
bandwidth by starting the task up the other three times, but this not only
gives you fine control over the task's period, but by extending this
technique you can give a task a very complex repetition structure.
Since you have the long long data type available, and since you can cascade
counters indefinitely, there's no limit to the period.
