PEP 703: Making the GIL Optional in CPython
This PEP proposes changes to the CPython build process that would allow you to build a GIL-less interpreter. This kind of interpreter would not be ABI compatible with the GIL-based one, and the programmer would become responsible for some locking situations in C-extensions. If implemented, this would lead the way to being able to operate without the GIL in cases where backward compatibility issues are not important.

Same Words, Different Meanings
One of the difficulties when comparing programming languages is that they sometimes use the same words to describe similar things, but always with differences. Sometimes the differences are large enough that we want to use different words, but often they are not.
