With 312 calls distributed across 100 meetmes, 'top' shows 1 core at 32%, 
1 core at 6% and the rest basically idle.

So it looks like meetme() is still a single CPU application, but I have 
plenty of CPU headroom.

Coincidentally, 512 is my target. Any clues on how to get 200 more?

Thanks in advance,
