[issue15488] Closed files keep their buffer alive

[Meador Inge]

Meador Inge added the comment:

The test should go in the 'SizeofTest' class and maybe a better test would be a variant of the test already in that class:

    @support.cpython_only
    def test_buffer_freeing(self) :
        bufsize = 4096
        rawio = self.MockRawIO()
        bufio = self.tp(rawio, buffer_size=bufsize)
        size = sys.getsizeof(bufio) - bufsize
        bufio.close()
        self.assertEqual(sys.getsizeof(bufio), size)

Otherwise, LGTM.
