I have not follewed this thread.  However the code above is far too
complex.  For years gpg-agent is able to test whether it is already
running, just call gpg-agent and don't pass the --daemon option:

  $ gpg-agent
  gpg-agent: gpg-agent running and available
  $ echo $?
  0
  $ GPG_AGENT_INFO= gpg-agent
  gpg-agent: no gpg-agent running in this session
  $ echo $?
  2



Shalom-Salam,
