python.com test_threading.py should pass

[ingenieroariel]

This may be a somewhat private api but it is used by Django.

https://docs.python.org/3/library/_thread.html#thread.get_ident

It is used here:

https://github.com/django/django/blob/stable/2.2.x/django/db/backends/base/base.py#L8

import threading
import _thread

        # Thread-safety related attributes.
        self._thread_sharing_lock = threading.Lock()
        self._thread_sharing_count = 0
        self._thread_ident = _thread.get_ident()

Actually Portable Python predates Cosmopolitan Threads support. You might want to try one of @ahgamut's more recent builds of Python. See https://github.com/shmup/awesome-cosmopolitan which lists https://github.com/ahgamut/cpython/tree/cosmo_py311 as the most recent. I'd be happy to merge a workaround for Cosmo's Python 3.6 if you send one. Thanks!

@ingenieroariel you might try the newer Python311 or try building python.com from this experimental branch: https://github.com/ahgamut/cosmopolitan/tree/python36-threads

I checked that the _thread module does work with a simple example, and moreover _thread.get_ident() does not error out

Wow @ahgamut awesome change! Reopening since we have an opportunity to get threading support fully working in the mono repo.

test_threading.py times out after 90 seconds. But when I ran it directly, it passed:
