Does the extension module release the GIL? It sounds like it does not. Of course, there are a dozen other mistakes that could be made which would have roughly this symptom. It's difficult to say which is the problem without actually seeing any code. >It looks like thread.Threading() only simulates threading, by having the >python interpreter multiplex between running threads.

Something else is going wrong. Jp -- http://mail.python.org/mailman/listinfo/python-list
