problem implementing a threaded module

[Stephane Conversy]

Hi. I'm trying to implement a C module that launches a pthread
and calla a python call-back.

I think it's not a big deal for those who know how to do it, but
my implementation does not work (seg fault).

I didn't really understand what to do exaclty:
should I create an interpreter state for each thread, using
PyInterpreterState_New ?
should I create a thread state for each thread with  PyThreadState_New and
swap
it with the current thread state ?

I can't figure out what to do. Is there any example that just creates a
pthread
and calls a python func ?

Thank you.
