IKImageBrowser performance issues

I'm having severe performance issues with the IKImageBrowser classes. I'm loading groups of around 100 images of decent resolution (one example is a group of 512x512 icons.) The rest of my app is based on CoreAnimation, and as soon as I start loading a new batch of images into the view, my CoreAnimation starts to stutter.

I'm aware that loading large batches of images is resource itensive, but I'm running on a dual core system with nothing else intensive running in the background. I would assume my IKImageBrowser image loads would be farmed to a different core than my CoreAnimation code.

Do I have any means of regulating IKImageBrowser*s CPU use? It's hogging the CPU in my app for a solid 5-10 seconds when I switch the items in the view, and I'm not sure the user will understand the reason for the CPU hit given that the visible images in the view will already be loaded.
