Not really.
The risk here occurs when you have a password stored in cleartext in
memory (for example, it is stored in the Lisp string just before we
are about to send it to gpg). If memory get written to the swap file,
it can be read by root.
If the passphrase is cached in Emacs, I presume someone walking up to
your terminal could type commands at Emacs and find it. Is that
right?
If so, does turning off caching prevent THAT problem?
If it does, should we document this? Or turn off caching by default?
Or what?
