Multi-threaded fluid baking?

Is fluid baking or any baking in that matter multi-threaded in Blender 2.53 beta? I’m barely using 13% of my Intel Core i7 and its going painfully slow when I bake.

As far as I know this kind of thing can not be multi threaded. It is a linear proccess, with each step being calculated after the other.

That is why I try to buy the processor with fastest cores instead of just many cores.

But I may be wrong here. I am not a programmer.
