For quite some time we've known that hibernation files present risks for
information security.  However, there are always those who say "until I
see an actual demonstration, I won't believe it."

The upshot: we now have an actual demonstration.  The takeaway is that
you should be very, very careful about hibernating your computer while
passphrases are cached, or while GnuPG is actively processing a file.
