This sounds good, thanks.

- I'm not sure it makes sense to have a fake-pinentry for each
  language (perl is not the only language with these issues I
  assume); would it be possible to ship something in the gnupg
  package itself that can be used by each package (by exporting some
  environment variable e.g.)?
- This still leaves the gpg-agent question; if I'm not mistaken
  gnupg2 will start a gpg-agent instance unconditionally -- and this
  one lingers on after the tests which is problematic for tests
  and/or in chroots.

My dream is something like
export HI_GPG_THIS_IS_A_TEST_DONT_ASK_PINENTRY_QUESTIONS_AND_CLEANUP_GPG_AGENT_THANKS=1
(maybe a bit shorter :)

Great, thanks alot!
