bpo-38630: Fix subprocess.Popen.send_signal() race condition (GH-16984) On Unix, subprocess.Popen.send_signal() now polls the process status. Polling reduces the risk of sending a signal to the wrong process if the process completed, the Popen.returncode attribute is still None, and the pid has been reassigned (recycled) to a new different process.
