 they can arise from doing I/O in a :mod:`signal` handler.  If a thread tries to
 renter a buffered object which it is already accessing, a :exc:`RuntimeError` is
 raised.  Note this doesn't prohibit a different thread from entering the
 buffered object.
 
 The above implicitly extends to text files, since the :func:`open()` function
 will wrap a buffered object inside a :class:`TextIOWrapper`.  This includes
 standard streams and therefore affects the built-in function :func:`print()` as
 well.
