In a way that there are might be empty CPUs? If so, yes, I agree.

Bringing this idea forward and combining with my next planned steps, I'd
suggest just adding another column, which would show the diff in time
between the clock and the timer expiration, preferably, in a
human-readable format (converted to seconds). Expired entries would go
with "-" sign.

What do you think?
