ConnectionLimitMiddleware doesn't call Dispose on SemaphoreSlim _limiter.
ConsumableArrayBufferWriter should be sealed or the Dispose should be virtual.
TimerAwaitable should be sealed or the Dispose should be virtual.
ConnectionContextWithDelegateis disposing the ConnectionContext connection, although it is injected.
SocketSender doesn't call Dispose on SocketAsyncEventArgs _eventArgs. Plus, the _eventArgs.Completed += (_, e) => ((SocketAwaitable)e.UserToken).Complete(e.BytesTransferred, e.SocketError); not a memory leak, as it never unsubscribed? This is the same with the SocketReceiver.
ServerConnection doesn't call Dispose on CancellationTokenSource _connectionClosingCts.
Server doesn't call Dispose on TimerAwaitable _timerAwaitable.
Noticed a few potential issues:
