This relates to previous questions regarding the GIL (Global Interpreter Lock) for Python on the Raspberry Pi. My question has to do with the new processor on the Pi 4 - does it still have the same restrictions as the Pi 3, where it cannot natively split a Python script into multiple cores?
This may be a fundamental misunderstanding on my part of the purpose of the GIL, but I was hoping maybe the Pi 4's new processor did not have this same restriction.
The Pi 4's new processor (Broadcom BCM2711) has four Arm Cortex A72 cores, whereas the Pi 3 had four Cortex A53 cores. They link to their preliminary datasheet here, but it doesn't seem to have much information on it.
Aside: There doesn't seem to be a Pi-4 tag, could someone please create it?

GIL is a design specification of the Python language, rather than a limitation of the Raspberry Pi [1] (multiprocessing is possible in Python, often with only a few lines of code [2], but multithreading is generally not). The new processor will have no effect on the limitations associated with GIL.
