It wouldn't be too hard to zero them immediately, I probably should. Someone will notice that things get slower... Also, when you reboot your machine, with ctl-alt-del, factotum's pages are still sitting in memory somewhere. Someone can load their own kernel and look at the data. I should also change ctl-alt-del to zero out process memory before bringing the system down. Then there are still crashes... Even with all that, I'ld be happier if the BIOS or boot ROM zeroed all memory.
