The idea is that the ThrottleState code itself doesn't know
anything about locks or groups. As I understood it Benoît

The throttle group support use a cooperative round robin scheduling algorithm.
The principles of the algorithm are simple:
- Each BDS of the group is used as a token in a circular way.
- The active BDS compute if a wait must be done and arm the right timer.
- If a wait must be done the token
