In addition to what the offer recommended in the "Scheduling work" section, using the `:timer.send_interval()` can be useful if you want to do something every X seconds, instead of every X + Y seconds, where Y is the time it takes to process the "work" message.

Also I prefer to use `handle_continue` instead of `schedule_work()` style (which in a lot of cases pre-date the introduction of `handle_continue`).
