Nope, I take it back. This allows it to work for a bit, but then I get
that same assertion error later:

It always happens when I see the first "p-warm" entry. I can run 4
clients at a goal of 100 without any problem, and the 5th one finishes ok,
but the server then crashes. If I move the server goal up, the p-warm
point moves up, as well - it's always 10% of the server goal. So
everything seems to work ok if I use an enormous server goal...
