Secure text editor?

Hello all,

I want to have a text file with personal data in it, which I encrypt to
myself, and decrypt to view and edit. However, to do that securely, I need
an editor which will not leak the text in any way, so locking it's pages in
memory so they won't be swapped out, and other angles of attack. In short,
an editor written with security in mind, suitable for editing sensitive
data. It's okay if it does that on plaintext files, I suppose, I can encrypt
and wipe the original to get rid of that, or do I miss something there?

My workstation runs Windows, but I think I would prefer a tool that works
under Linux too (possibly under Cygwin in Windows). It would be cool if it
integrated with GnuPG so I don't have to manually en- and decrypt, but it's
not a demand unless, like I said, I missed some vector of attack.

Does anybody know an editor that's up to the job?

Regards,

Peter Lebbing.
