[issue10554] Context managerment support for subprocess.Popen

[Éric Araujo]

Éric Araujo <merwok at netwok.org> added the comment:

New doc looks good. Suggested changes: make with a link, explaing why it’s a context manager.

-   Popen objects are supported as context managers via the ``with`` statement.
+   Popen objects are supported as context managers via the :keyword:`with`` statement, so that file descriptors are closed cleanly.

I agree with your view on __del__ vs. __exit__.
