Then it should play nicely with Python. But keep in mind that thread 
switches can also be blocked by some thread without having the GIL locked.
We've seen such situations were a thread had to perform complex regular 
expression matching operations. Obviously code in Python C extension is 
also able to lock up the Python interpreter until the result is being 
passed back to the Python interpreter.
