Close transports
----------------
When a transport is no more needed, call its ``close()`` method to release
resources.
If a transport (or an event loop) is not closed explicitly, a
:exc:`ResourceWarning` warning will be emitted in its destructor. The
:exc:`ResourceWarning` warnings are hidden by default: use the ``-Wd`` command
line option of Python to show them.
