That could work. Another advantage: we could use the slab allocator to
allocate the task_struct then which does proper L2 cache colouring ->
better cache usage.
(it does L1 coloring...)
I did this by hand on the Ultra to see what the effects would be on
things like ctx switch latencies etc.
The results were that the coloring made no difference at all (I tried
both L1 line size and L2 line size for the colors).
