I think it should either ignore queues that are always zero (beyond the number of CPU cores), or always reserve last few lines for summary output, effectively cutting off few queues from bottom when the terminal window doesn't have enough lines for all queues + summary.

Thanks for the report - I wouldn't like to have to reserve space at the bottom of the screen, but I'll consider ways in which I can ignore queues that have no data in them.
