Small clarification, in case it makes a difference for anyone searching later.
I had inlined `server-eval-at' to try and root cause, and it
looked to me like the call to `accept-process-output' here:
https://github.com/emacs-mirror/emacs/blob/e3661f8c35b3057c58e8c0b474f597697ce413ba/lisp/server.el#L1737
was necessary to trigger the unexpected behavior. Without that call,
subsequent calls to `read-string' did not hang.
