I think you have read too much glossy marketing PDFs :-) All we know is that VM *could* see it as free and we know it's not always looking for it at that place. And in fact, in this case Holy Page Management Assist is likely to do the thing. I second Mark that CMM-1 is the thing immediately frees the backing pages in z/VM. I use it on my test servers to reduce the footprint when I am done with my tests. It's not true that CMM-1 involves another virtual machine to do that (only if you choose to use VMRM to steer CMM).
