It IS a significant boost, but relatively meaningless one. It seems like
an enourmous waste of effort to implement for what is essentially zero
real world gain.

I'm actually pretty surprised there is such a large difference. On x86
at least, Q3 is a long way off CPU bound and as such parallelising it
doesn't really result in a much of a gain. I guess this goes to show
that the OS X build is somewhat less efficient CPU wise. It will be
interesting to see how OS X/x86 performs.
