Memory leak in aioquic

[guest271314]

Let's say the requirement is to write exactly one (1) datagram to server, and for the server to send a continuous stream of datagrams to client (in this case WebTransport on Chromium 100) until transport.close() is called. Basically, streaming media https://github.com/aiortc/aioquic/pull/262.

What I observe is that the http3_server.py sends a maximum of 28 datagrams to the client , then the connection is lost. 

However, http3_server.py memory consumption continues to grow exponentially until CTRL+C is pressed.
