But you can use `add-function` to avoid the problem: (add-function :before (process-sentinel (get-buffer-process (get-buffer eepitch-buffer-name))) (lambda (_process event) (when (equal "finished\n" event) (run-with-idle-timer 1 nil after)))) Adding elements (IOW, "multiplexing" the sentinel) to a process sentinel was actually the problem that spurred the development of `nadvice.el`. 🙂 Stefan
