So if I'm not wrong when before_fork block is runned the $stderr is already 
redirected to the IO set in "stderr_path", rigth?
Then any error in the config file into before_fork would not vi raised to the 
terminal screen but to the stderr (if it has been redirected).

Then I see no advantage on using what you suggest ("if worker.nr == 0 ...") 
over adding such code at the top of the config file. Do I miss something?

Thanks a lot.
