…honGH-152976) The hang this test guards against (interpreter exit after shutdown(wait=False) with running futures) was fixed for ProcessPoolExecutor by the executor management rewrite years ago, but the test still skipped it citing the issue. The skip also hid a latent NameError in the subprocess template, which only selects a start method in the process pool variants; rewrite it to use the same mp_context=get_context() shape as the sibling templates. Remove a stale comment claiming ProcessPoolExecutor often hangs with wait=False. (cherry picked from commit 548c731) Co-authored-by: Gregory P. Smith <68491+gpshead@users.noreply.github.com> Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
