Thanks for answering Tim, but I don't really know if I need to use these
functions, what I need is how to run different python "applications" from
the same process. When I say applications I mean like for instance
PyRun_SimpleFile. These applications must not share things like sys.stdout
for instance because I am going to assign it to different objects for each
thread. Does these requirements mandate using something like
Py_NewInterpreter or can it be achieved in other ways.

NB. This is my first shot at using the Python C interface so there are
probably obvious things I haven't grok'ed yet, but I know C++ well.
