The problem I see here is that the 'finish' event might be emitted before buffered data is flushed and similarly the outgoingMessage.end() callback might be called before previous outgoingMessage.write() callbacks.

I understand, but I think at this point there should not buffered data and a consecutive call to end() should not reach here, or am I missing smthg? Thanks

What do you think about adding a check for socket.writableLength to the above else if branch?
...
} else if (!this._headerSent || this.outputSize || chunk || this.socket?.writableLength) {
this._send('', 'latin1', finish);
} else {

That sounds good. We might even use OutgoingMessage.writableLength directly. Thanks!

I think you are right because the transfer encoding would be chunked but I'm not sure if there are cases where that path can be taken anyway. For example in #41062 the user specifies the Content-Length header so the chunked encoding is not used.
When calling OutgoingMessage.end() with empty data argument, avoid writing to the socket unless there's still pending data to be sent. Fixes: nodejs#41062
