In which case it is because of the adding of both the parent directory
and the project directory to sys.path, plus some module somewhere (not
in project directory) importing just 'settings', instead of
'myproj_foo.settings'.
People who always properly qualify module references in urls.py and
elsewhere via the name of the project wouldn't have this problem. It
is only where people try and write code which is somehow independent
of the project name where it would be an issue.
