Thanks for the work. I will try it out later today.

It seems list-processes no longer cleans up dead processes. How about
adding something like:

  (mapc (lambda (p)
        (when (memq (process-status p) '(exit signal closed))
          (delete-process p)))

towards the end of list-processes in the patch?¹

Also, some people ask to be able to visit process buffers. Maybe we
should also bind RET to visit the process buffer under point?
