Thank you for the clarification. This non-blocking behavior is indeed required.

I'm aware of all this but this is still WIP (the tag is missing, my
mistake). Also, the goal is not necessarily to implement the complete
RFC for now. For instance we could let the user handle the 3xx status
codes for now.
You are right that there are a few missing cases here when handling
the response and we shouldn't make any assumption on what we might
receive, but I wanted to send a new (incomplete) iteration for review
since the patch is already pretty large.
