> The Scheduler Library doesn't manage to keep the schedules running. Some seems to get lost, and many are never run at all.
> I have modified the existing test case to show that being the case. Below, the task is only run once.
> From my app, I am pretty sure it doesn't matter whether it is the same Task instance or separate instances... They get lost...
