Issue where I hit this is in Fail2Ban: https://github.com/fail2ban/fail2ban/issues/687

Lines of code where this occurs: https://github.com/fail2ban/fail2ban/blob/1c65b946171c3bbc626ddcd9320ea2515018677b/fail2ban/server/server.py#L518-530

There are other examples of closing file descriptors in other packages which create daemon processes, as well as code snippets about, as it is typical behaviour to close files. (http://en.wikipedia.org/wiki/Daemon_%28computing%29#Creation)
