Perfectly valid thought. Hence allocWithZone:, which, in theory, allocates blocks in a specific area and reduces paging loads, among other things. how effective it is, I'm not entirely sure, but I tend to do it anyway (call me anal and paranoid, but...)

Mind you, if your app(s) are thrashing VM, buy more ram![1]
