[$] An explicit thread-safety proposal for Python

Mon, 03 Nov 2025 17:44:17 +0000

Description:
Python already has several ways to run programs concurrently 
including asynchronous functions, threads, subinterpreters, and 
multiprocessing
 but all of those options have drawbacks of one kind or another. PEP703 
("Making the Global Interpreter Lock Optional in CPython") removed a major 
barrier to running Python
threads in parallel, but also exposed Python programmers to the same tricky
synchronization problems found in other languages supporting multithreaded
programs. A new draft proposal
by Mark Shannon, PEP805 ("Safe Parallel Python"), suggests a way for the 
CPython runtime
to cut down on concurrency bugs, making it more practical for Python 
programmers
to use versions of the language without the global interpreter lock (GIL).
