In mono/.net I guess we'd have to queue GCHandles instead of
WeakReference objects: would that work for you?
Also: how do you think the API should look like in C#?
How is the access to this queue regulated for different subsystems?
Who removes the entries from this queue? Are all the handles posted or
just the ones that are specially registered?
Maybe we want an event where the users can register a delegate?

	delegate void ZeroedHandles (GCHandle[]);
