Released the GIL

Browse Source 
# New Document
released the GIL to make use of multiple cores when using multithreading.

as per [the docs](https://docs.python.org/3/c-api/init.html#releasing-the-gil-from-extension-code):
>Calling system I/O functions is the most common use case for releasing the GIL, but it can also be useful before calling long-running computations which don’t need access to Python objects, such as compression or **cryptographic functions operating over memory buffers**. For example, the standard zlib and hashlib modules release the GIL when compressing or hashing data.
