Comment 9 for bug 793096

regarding gpg-agent:

i just really tried it for the first time and it is quite simple under linux. unfortunately it does

- not allow to add keys. you have to encrypt/sign something and it asks for password then.
- not save passes forever. by default they seem to be cleared after 600 seconds. there is no way to disable this cache invalidation, although there are options to lengthen the period.
- not play well with gpg --passphrase-fd 0. actually my gpg 2.0.9 doesn't. --passphrase-fd has priority over --use-agent resulting in wrong secret errors. as GnuPGInterface.py is using this method of pass delivery it is obviously _incompatible_ with gpg-agent at all, although one might be lucky, maybe other gpg versions behave better.

so far ede
