OK, let me know what you find out.

I didn't change the logic if/when SSL_accept() fails, because if its an 
SSL_wrapped process, there is nothing to fall back on (the application 
protocol hasn't started yet).  Perhaps your dial-in clients take longer 
than 3 minutes to complete the handshake.

Hmm, from this particular log, I don't see the debug message tellinng us 
that we're waiting for more input.  When I test locally (over 
localhost), I always get at least in "-> waiting" log message before the 
"-> done" messsage.
