    Summary: tokio-rustls reads may cause excessive memory usage

    Details: `tokio-rustls` does not call `process_new_packets` immediately after `read`, so the expected termination condition `wants_read` always returns true. As long as new incoming data arrives faster than it is processed and the reader does not return pending, data will be buffered. This may cause DoS.
