Description

Feature or enhancement

Proposal:

The buffered I/O module currently uses the obsolete PyThread_type_lock. I propose migrating it to the more performant PyMutex.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

    PyThread_type_lock is a PyMutex.
