[issue17634] Win32: shutil.copy leaks file handles to child processes

[R. David Murray]

R. David Murray added the comment:

Unless I'm misunderstanding something, this has already been fixed in python3, where subprocess closes any open files (other than stdin/stdout/stderr) by default.  In Python2.7 (and possibly earlier, I haven't checked) you can get the same effect by specifying close_fds=True in the Popen call.

I don't see any reason why shutil should take any special action in this case, this is a general problem with open file descriptors and subprocess.
