Yeah, that's true -- a counter wouldn't help at all here.
Would checking the size of the `process-buffer' of the process be more
helpful? It might be a somewhat unnatural thing to do -- Emacs doesn't
give you a warning if you say
(dotimes (i 100000000) (insert (make-string 80 ?a)))
so perhaps that's not a good heuristic, either.
So bytes/sec, as you suggest, may be the best heuristic. But it should
only kick in after having received a large number of bytes, probably.
