First of all, you need some other method for debugging, or a way 
to make sure that stderr is not closed in your particular setup.  
Normally nginx closes stderr while becoming a daemon, so it's 
expected that printing to stderr won't work.

Normally one should use ngx_log_error() and/or ngx_log_debugN() 
to print log and/or debug messages.
