"""
Use a Timer to react to events in another thread
------------------------------------------------
You should never modify Blender data at arbitrary points in time in separate threads.
However you can use a queue to collect all the actions that should be executed when Blender is in the right state again.
Pythons `queue.Queue` can be used here, because it implements the required locking semantics.
