#c_lang jemalloc is a memory allocator that helps computers manage memory more efficiently. It was first used in FreeBSD in 2005 and is now used in many applications because it reduces memory fragmentation and supports many threads running at the same time. This means it can handle lots of small memory requests without slowing down, making it very useful for demanding applications. The benefit to users is faster and more reliable performance, especially in programs that need to handle a lot of data or run many tasks simultaneously. https://github.com/jemalloc/jemalloc

https://wiki.python.org/moin/GlobalInterpreterLock In #CPython, the #global#interpreter lock, or #GIL, is a mutex that prevents multiple native #threads from executing Python bytecodes at once. This lock is necessary mainly because CPython's memory management is not thread-safe. (However, since the GIL exists, other features have grown to depend on the guarantees that it enforces.)

https://docs.python.org/3/library/atexit.html The #atexit module defines #functions to #register and #unregister cleanup functions. Functions thus registered are automatically executed upon normal interpreter termination. atexit runs these functions in the reverse order in which they were registered; if you register A, B, and C, at #interpreter#termination time they will be run in the order C, B, A.
