Thanks for the fast response!

There is a paragraph right at the end of <https://docs.python.org/3/library/socketserver.html#server-creation-notes> that mentions this technique: “. . . maintain an explicit table of partially finished requests . . .”. Perhaps that is the suggestion that you couldn’t find before.

I once wrote an RTSP proxy that uses a related technique. It still handles each high-level RSTP request or RTP packet synchronously, but uses the “selectors” module to switch between the various connections and listening sockets after each high-level request had been handled. Code at <https://repo.or.cz/python-iview.git/blob/refs/heads/rtsp:/iview/utils.py#l318>.

Do you want to propose some specific additions or a patch to the documentation?
