Message10028

Hello! This bug is biting my application which uses Py.setSystemState(). I was wondering what would be the best fix and I wonder if the following would be OK:

We change the code to be that of msg9795 (no weak values) but then we store the provided *PySystemState* to a WeakReference with a ReferenceQueue.

And then we use the associated ReferenceQueue to detect when the PySystemState is garbage collected so that we can remove the associated ThreadState from the map...

BTW, I was never really clear whether sharing the PySystemState between two threads was safe or not (this is where documenting the API would be helpful!).
