I suspected it might be a buffering problem, and the docs for
GnuPG::Interface state in the FAQ:
"When having GnuPG process a large message, sometimes it just hanges there.
Your problem may be due to buffering issues; when GnuPG reads/writes
to non-direct filehandles (those that are sent to filehandles which you
read to from into memory, not that those access the disk), buffering
issues can mess things up. I recommend looking into "options" in
GnuPG::Handles."
Your code did not appear to turn off buffering for the handles, can you
try this and see if it fixes the issue? I tested G::I on much bigger
files fo1r performance issues without problems, but always used
unbuffered handles.
