Tick N:

        stolen and blocked will not get incremented, while
        the per-cpu processed_time gets 2 jiffies

But we decrement delta_cpu *before* rounding down. So, after handling stolen and blocked, we'll end up with delta_cpu==0.6 which gets rounded down to 0 and so per-cpu processed_time gets 0 jiffies?
