Re: PEP 3143: Standard daemon process library (was: Writing a well-behaved daemon)

be interesting is keeping file descriptors from the logging module open by default. So that you can setup your loggers before you daemonise --I do this so that I can complain on stdout if that gives trouble-- and are still able to use them once you've daemonised.

C API and memory allocation

Arg_ParseTuple() must allocate new memory for the returned string. However there is nothing in the API that provides for freeing that allocated memory again.
