Avtually, a spinlock would probably not even be feasible in Python: The 
GIL is a mutex, and we would have to give it up before we could spin on 
the lock, and reacquire afterwards. So the cost of a kernel mutex object 
is still there. The gillock is possibly the only way of getting a fast 
lock object in Python.
