This (and the change to gnupg2) has now broken dgit's DEP-8 test
suite, when run under schroot. I'm discussing this in #840669 (CC'd).
I am trying to persaude Daniel that we should provide (at least
optionally) a mode where an autostarted agent (and the corresponding
authorisations, if the user types in a passphrase) have a lifetime
limited by that of the gpg process which started the agent.
