Multithreading isn't really possible with Python. The Python docs clearly 
state that the interpreter is not reentrant and therefore a multithreaded app 
must actually care about locking interpreter entry properly. So multithreaded 
Python scripts are not possible with the "normal" C Python interpreter.

There is another Python interpreter written in Java, which I'm using for 
Moonlight, my own modelling/animation project. This one should be able to run 
multiple threads concurrently, but hasn't quite kept pace with implementing 
new language features, as I was to find out today.
