If a `close_notify` alert is received during a handshake, `complete_io` does not terminate. Callers which do not call `complete_io` are not affected. `rustls-tokio` and `rustls-ffi` do not call `complete_io` and are not affected. `rustls::Stream` and `rustls::StreamOwned` types use `complete_io` and are affected.
