What problem does the GIL solve for Python?
To avoid race conditions, and consequently, the corruption of value reference counts, the GIL is implemented so that only one thread can access and mutate the counts at any given time.
What problem does the GIL create for Python?
The GIL effectively prevents multiple threads from taking advantage of the CPU and executing CPU-bound instructions at the same time. This means that if multiple threads that are meant to be executed concurrently are CPU-bound, they will...
