[issue43579] Leak in asyncio.selector_events._SelectorSocketTransport

[begnac]

New submission from begnac <candeb at free.fr>:

Hello,

Even after close()ing, asyncio.selector_events._SelectorSocketTransport keeps a reference to itself via self._read_ready_cb.

should probably add

def close(self):
    super().close()
    self._read_ready_cb = None

Cheers !
Itaï.
