I am not so sure is it practical to use tasking on Arduino/Atmega328P.
For example, if you have 4 tasks and divide memory equally, each task
gets only about 512 bytes (2KB total / 4 = 512b and you need to
reserve a little for the scheduler also). In addition, task switching
overheard might become quite big, since you need to save quite many
registers in every switch and processor CPU frequency is limited to
20MHz at maximum.
But, I agree that (implementing) the tasking would be interesting,
whether or not it being useful. :)
