As you note, and as discussed on IRC, this is not OK because the private
key ends up being stored world-readable in the store.  :-/

Am I missing the part you wanted to discuss?

Thanks,

PS: I still intend to look at the patch series you sent ;-), just
    prioritizing things that relate to 0.9.1.
