Hola Jose, el problema que describes es la razon de por que existe el metodo copy.copy() y copy.deepcopy() de la documentacion:
https://docs.python.org/2.7/library/copy.html """ - A *shallow copy* constructs a new compound object and then (to the extent possible) inserts *references* into it to the objects found in the original. - A *deep copy* constructs a new compound object and then, recursively, inserts *copies* into it of the objects found in the original. """ Y para el objeto logging: https://docs.python.org/2.7/library/logging.html?highlight=logging#thread-safety """ The logging module is intended to be thread-safe without any special work needing to be done by its clients. It achieves this though using threading locks; there is one lock to serialize access to the module’s shared data, and each handler also creates a lock to serialize access to its underlying I/O. """ En este caso, probablemente deberas usar un copy() en vez de deepcopy. Espero haberte ayudado. Un saludo.
