Didn't I ever say:
- Once an attacker successfully takes over your desktop session, he can
do almost everything. We can't do much on that situation. Why don't
you lock the screen before leaving?
- More possible threat is inspecting persistent data (e.g. core files on
a disk attached to a stolen note PC). GnuPG is designed to be secure
against this, using "secure core".
- On the other hand, Emacs copies small strings around. If passwords
(normally not too long) are managed poorly in Emacs, they might appear
repeatedly in a core file, when it crashes.

Interesting. Any prior art on that area? I haven't heard the word
"tainting" used in that way. Isn't it for preventing untrusted data
being injected to, say, SQL?
