Use when dealing with Blender Python runtime behavior -- mathutils, threading, handlers, timers, or crashes after undo/redo. Prevents the #1 runtime crash: using threading for bpy operations instead of bpy.app.timers, or caching bpy.data references across undo boundaries. Covers Vector/Matrix/Quaternion, KDTree, BVHTree, @persistent handlers, bpy.msgbus subscriptions, and background mode limitatio
