hm, what affinity do they start out with? Could they all be pinned 
to CPU#0 by default?

They start off with affinity masks of 0xf on a 4-CPU system.  I would 
expect them to load-balance across the four CPUs, but they stay all on 
the same CPU until long after I lose patience (many minutes).

ugh. Would be nice to figure out why this happens. I enabled rcutorture 
on a dual-core CPU and all the threads are spread evenly.
