subprocess.Popen now copies the startupinfo argument to leave it unchanged: it will modify the copy, so that the same STARTUPINFO object can be used multiple times. Add subprocess.STARTUPINFO._copy() private method. Python 3.7 backport from master makes the copy() private: renamed to _copy(). (cherry picked from commit 483422f)
