1) You're right -- I am comparing the elements in Size and Wired from kextstat. My understanding is that if a kext is leaking, then the allocated bytes and those that the kernel knows are allocated will be different. In this case, I've put that there to show that I don't have a leaking kext -- so, 2) this doesn't occur when Preview eats ram. Instead, kernel_task grows a lot. I'll try and recreate this issue and take a picture :-).

I'm confused about two things -- could you clarify? 1) I think your diff command is comparing the Size and Wired columns from the kextstat output. I agree that Size is "allocated memory", but I don't think Wired is "expected to be allocated" (man kextstat describes it as "The number of wired bytes of kernel memory that the kext occupies"). 2) Are you seeing the discrepancy between Size and Wired when you have the issue with Preview?
