>>> f = open("LICENSE", "rb")
>>> sys.getsizeof(f)
4296
>>> f.close()
>>> sys.getsizeof(f)
4296
Instead of waiting for the file object's deallocation, perhaps we should free the buffer when it is closed?

Sounds reasonable to me. |

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.

This has to wait for 3.4, since it's an enhancement, not a bug. |
