The memory is cleaned before another process gets it but that could be
too late in the presence of bugs. 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.
