Chiming in:
Multi-core requires love to work well.
ImageMagick, for example, has been known to run considerably faster on busy
systems with openMP disabled.
In GIMP 2.6, frequent marching ants were a CPU sink. (Bad observer

All you have to do is set marching ants speed to 10 and watch it ramp up
the CPU.
Perhaps setting marching ants speed to 0 should simply disable the updates
altogether? Generate the ants at one time, and don't bother updating them
again...
