Are you saying that the response comes over the wire and that curl somehow
holds on to it? There's no such functionality in curl at all so it would
greatly surprise me.

It waits for the response.

How do you tell this is curl's fault and not the server's? Curl won't add any
additional wait when doing Expect: - excluding that initial 1000 ms wait it
might do - until it proceeds nonetheless.

Have you done some wiresharking or similar on the connection to properly put
the blame on curl for this? If so, can you share some TCP/HTTP tracing details
with us on this subject?

Sure, it is discussed widely. And I would even claim that it is also mostly
concluded that the errors exist in the server end...

This makes me curious, but the lack of details prevents me from making any
valuable conclusions.

Can you elaborate in detail how the requests between a modern curl version and
"HttpClient" differs when it comes to this?
