My first thought in approaching this problem, is to do it on a ramdisk (or whatever they are calling them nowadays). Make a ramdisk (google for how), run everything on it, then write 0's over it when done. Write 0's over your swap space too.

Another idea is to mount a virtual filesystem via loopback (it's essentially a single file that acts like a filesystem.... google for that too :-) ) Then delete the file when done (overwrite with 0's first). There are even encrypted loopback filesytems you can work on for security. By the time you get to encrypted loopback filesystems, there are easier ways to hack you.
