FTR, I ran this against the buildbots and there were two failures:

aarch64 RHEL8 Refleaks - https://buildbot.python.org/#/builders/802/builds/1730
wasm32-wasi Non-Debug - https://buildbot.python.org/#/builders/1373/builds/503

Neither looks related, but I'll rerun them just to be sure.

!buildbot PPC64LE RHEL8 LTO + PGO

bedevere-bot · 2025-06-06T21:49:08Z

The regex 'PPC64LE RHEL8 LTO + PGO' did not match any buildbot builder. Is the requested builder in the list of stable builders?

I'll merge this once I've verified that buildbot passes.

Lib/test/test_threading.py

 try:
-fromtest.supportimportinterpreters
+fromconcurrentimportinterpreters
 exceptImportError:
 interpreters=None


Do we have a reason to expect this import will fail, or can we remove this condition? (Here and elsewhere.)

Probably if _interpreters doesn't exist.

Currently the module isn't supported on WASI and Emscripten builds. See gh-135190.

And I've been waiting for Eric to try to turn it all on -- at least for WASI -- and see if it just works. 😉
