Yep. Sounds good.

I've also come to appreciate that my description in the general.ent of 
the parallel building may not be accurate.

On my machines, I can't get any performance improvement past -j3. This 
is true of both my single processor machines and my SMP's. I haven't 
tested with distcc, so that might be a different story, but for a single 
machine, with or without SMP, -j3 is about as high as you can expect to 
go and get any benefits.

That disagrees with my previous understanding of the parallel building.
