I am scientific Python programmer. 99% to 100% of my programs require parallelism, but it is ALWAYS embarrassingly trivial parallelism, nothing is ever mutated and I never need locks. Right now I am forced to use multiprocessing to get the performance, with all problems of multiprocessing, the major one being that I need to use more memory. For me using multithreading could mean the difference between running out of memory and not running out memory. The GIL removal matters for people like me, the proponents of the GIL removal comes from the scientific community.
