the problem is that Mail::GnuPG sends the whole message to gpg before
reading any of its output. With large messages the pipe buffer fills up
and both processes will block on write().
The same problem is also present when decrypting; it's reported upstream
in rt.cpan.org tickets #21302 and #21276.
The Mail::GnuPG code needs to interleave the reading and writing with
a select() loop. I have a patch almost ready, I'm just looking at
integrating it with a better fix for #412041.
