Client desctructor never called in Maya

[darkKatze]

Hello,
We are trying to set up a custom resolver based on your turret-resolver.
Everything works well except the fact that if we use the plugin in Maya, the client resolver destructor (in turretClient.cpp) is never called (if we close the scene or when we close Maya). It's a problem because it means that the cache is never written.
How do you face this issue when you use the resolver in Maya?

Thank you
