There was a patch for Linux to scramble memory just before halt. However
it has not been pushed to developers nor incoroporated into the Linux.

Unfortunatelly, I cannot find it now. It's few years old code. I rember
it had solved more problems than just this one and that the patch
touched halt(8) utility and kernel.
