YAML - !Yet another memory leak! Opened a PR to fix the non exisiting issue

Can someone from the maintainers check the PR I created. Its a simple addition to multiprocessing doc. The RCA is not DEAP but the simple quickstart that most follow. #753

This is not an issue with deap but with the general understanding of multiprocessing. It does not just happen with deap, but with any combination of libraries using multiprocessing/threading. It also happens when you combine torch multi loader and numpy. I dont think a warning in comment will help, but this issue might be a better place.

So beware, whe using multiprocessing any underlying library might also launch N processes/threads based on some environment variable or else. In case of numpy the most common environment variables to control the number of threads are OMP_NUM_THREADS and MKL_NUM_THREADS.
