PGP swap to disk?

[Art Hampton]

My admin is balking at making GPG setuid root to prevent swaps to disk.

He says that he's used PGP before, and that it didn't need to be setuid
root.

I seem to remember this conversation coming up on this list before, but
it doesn't look like lists.gnupg.org supports searches.

Is it the case that PGP doesn't address this particular issue, and
therefore swaps to disk can occur?

What attack is being countered by preventing a swap to disk?


Thanks in advance for any help.
