Not if the idea that lead to this thread (clearing ticker if something 
is put in things_to_do)
is implemented, because we may be in an interrupt routine at the time we 
fiddle things_to_do.

And I don't think we can be sure that even clearing is guaranteed to 
work (if another
thread is halfway a load-decrement-store sequence the clear could be 
lost).
