…onGH-16552) Motivation for this PR (comment from @vstinner in bpo issue): ``` Warning seen o AMD64 Ubuntu Shared 3.x buildbot: https://buildbot.python.org/all/GH-/builders/141/builds/2593 test_devnull_output (test.test_a=syncio.test_subprocess.SubprocessThreadedWatcherTests) ... Warning -- threading_cleanup() failed to cleanup 1 threads (count: 1, dangling: 2) ``` The following implementation details for the new method are TBD: 1) Public vs private 2) Inclusion in `close()` 3) Name 4) Coroutine vs subroutine method 5) *timeout* parameter If it's a private method, 3, 4, and 5 are significantly less important. I started with the most minimal implementation that fixes the dangling threads without modifying the regression tests, which I think is particularly important. I typically try to avoid directly modifying existing tests as much as possible unless it's necessary to do so. However, I am open to changing any part of this. https://bugs.python.org/issue38356 (cherry picked from commit 0ca7cc7) Co-authored-by: Kyle Stanley <[email protected]>
