I'm not sure I understand what you mean here.  The point was to use
gnutls_certificate_set_x509_key_file2 instead of
gnutls_certificate_set_x509_key_file in gnutls.c -- so that should be an
internal change in gnutls.c that nothing else should need to know about.

process.c has an abundance of comments already, but if there's further
comments that would be helpful, that's welcome, of course.
