If a file-like object passed as *stdin*, *stdout* or *stderr* represents a
pipe, then the other side of this pipe should be registered with
:meth:`~loop.connect_write_pipe` or :meth:`~loop.connect_read_pipe` for use
with the event loop.

See the constructor of the :class:`subprocess.Popen` class
for documentation on other arguments.
