> Literally, there is an initiative to introduce multiple GILs to CPython. It's called subinterpreters. The idea is to have multiple interpreters within the same process. Threads within one interpreter still share the GIL, but multiple interpreters can run parallel. No GIL is needed to synchronize interpreters because they have no common global state and do not share Python objects. This sounds very much like Ruby's recently introduced "ractor", no?
