Yeah, a background process with parent PID 1 and not associated with any terminal group. But is that relevant to the PEP? A daemon only uses fork(), not exec(). Or have I misunderstood your concern?

Actually it's common for "daemonization" libraries to run an arbitrary executable as a daemon, and then it would be relevant. E.g. zdaemon (https://pypi.python.org/pypi/zdaemon) does this. (Disclosure: I wrote the first version of zdaemon when I worked for Zope Corp over a decade ago. :-)
