Use :meth:`communicate` rather than ``.stdin.write()``, ``.stdout.read()`` or
``.stderr.read`` to avoid deadlocks due to any of the other pipe buffers
filling up and blocking the child process.

If the *stdin* argument is ``PIPE``, this attribute is a file object that
provides input to the child process. Otherwise, it is ``None``.
