Yes, but as far as I can tell, the compiles don't always happen in
parallel. I never see more than 1 compile process at a time on my
(single core) machine.

On my sluggish PowerBook G4 / 512 MB, 7 file project:

- ppc only:   50 Sec.
- universal: 110 Sec.

GCC probably makes a different decision on a multi core system. So maybe
the solution is to disable one core ;-)
