[twisteroid ambassador]

New submission from twisteroid ambassador <twisteroid.ambassador at gmail.com>:

When running the built-in regression tests, although test_sendfile_close_peer_in_the_middle_of_receiving on ProactorEventLoop completes successfully, an InvalidStateError is logged.

Console output below:

test_sendfile_close_peer_in_the_middle_of_receiving (test.test_asyncio.test_events.ProactorEventLoopTests) ... Exception in callback _ProactorReadPipeTransport._loop_reading(<_OverlappedF...ne, 64, None)>)
