Isnt't that the problem with almost any data? At some point you have to
decrypt it to edit or view it with some application. Be it an email
message, a text file, a picture, or a PDF file. And during this process
decrypted data will be stored temporarily in memory or on the disk. I
think demanding all allplications to be aware of this and to handle it
securely is quite a strong requirement, although somehow reasonable.
(And as always, it depends on your threat model of course.)

I don't know, for example, how it is done in the Enigmail plugin. Does
it prevent Thunderbird to write unecrypted data to memory that could end
up in a swap file?
