+**NOTE on concurrent usage:** The `Minio` object is thread safe when using the Python `threading` library. Specifically, it is **NOT** safe to share it between multiple processes, for example when using `multiprocessing.Pool`. The solution is simply to create a new `Minio` object in each process, and not share it between processes.
