Content
While debugging bpo-39877, I was surprising that Python crash was only noticed on FreeBSD by a side effect. On FreeBSD, coredump files are created in the current directory. But Python regrtest fails if a test creates a file and doesn't remove it. I found that multiprocessing.Process.join() deletes the subprocess.Popen object as soon as the process completes, but it doesn't log any warning if the process is killed by a signal. The caller has no way to be notified. I propose to enhance Process to log a warning if such case happens.
