Thank you very much. That's exactly what I was looking for.

I think I didn't describe correctly what I'm doing. I have a server 
written in Python which starts another process (a C++ program). This 
process takes some time to complete and I want to periodically ask the 
server whether the process has finished. Meanwhile I want to make other
computations on the client side (Python with C-extensions) and 
communicate with the server.

Thanks again
