[New-bugs-announce] [issue31009] test_multiprocessing_spawn hangs randomly on AMD64 Windows10 3.x

[STINNER Victor]

New submission from STINNER Victor:

Same question as usual: why regrtest doesn't display the "running: test_multiprocessing_spawn (319 sec)" update every 30 seconds? Is regrtest main process also stuck?
