The rate of flattening out appears to correlate with the number of processes

With only 'gdm' running, things flatten out slowly, iow, it takes longer
delays to see recvfrom slow down. With only 1 process running (init=bash),
the graph is nearly flat.

I'm trying to figure out which processes have the most impact, I had already
killed anything non-essential. But that still leaves 140 pids.
