functools.lru_cache prevents function being cached from executing concurrently under free-threading #131757
Description
Feature or enhancement
Proposal:
functools.lru_cache was made free-thread safe but is not so in an efficient way. It works currently by serializing the function being cached and preventing it from executing concurrently even if it can. Effectively, for the function being cached, it is as if the GIL still exists.
Has this already been discussed elsewhere?
This is a minor feature, which does not need previous discussion elsewhere
