You actually have a more severe problem.  The session is already established
and so the renegotiation must happen over an already encrypted channel.  But
there's no API to export the cryptographic state for use in the new executable.

I believe you're out of luck.  I believe that OpenSSL does not support migration
of live connections between address spaces.
