 :pep:`446` makes newly created file descriptors :ref:`non-inheritable

+<fd_inheritance>`.  In general, this is the behavior an application will
+want: when launching a new process, having currently open files also
+open in the new process can lead to all sorts of hard to find bugs,

+However, there are occasions when inheritance is desired.  To support

 * :func:`os.get_handle_inheritable`, :func:`os.set_handle_inheritable`
