FWIW, I implemented [something similar in Jupyverse](https://github.com/jupyter-server/jupyverse/blob/1daa47cb08e4c79ee6e22dcd6dd2857dc01f886b/plugins/terminals/fps_terminals/server.py#L91-L119) (part of https://github.com/jupyter-server/jupyverse/pull/388).

But I think you're right that it should be part of AnyIO, if Trio has this feature.

Let's continue the discussion from https://github.com/ipython/ipykernel/pull/1079#issuecomment-1974020784 here, maybe @agronholm has ideas.
