1) Create a file count.sh
#!/bin/bash
ctr=0
while true; do
sleep 1
echo "ctr = $ctr"
ctr=$(( ctr + 1 ))
done
2) Create a buffer called *count*
3) Start count asyncronously from a clean emacs (-q)
(defun Tmp.filter-fun (proc s)
(with-current-buffer "*count*"
(insert s)))
(defun Tmp.count ()
(interactive)
(let ((process
(start-process
"count"
"*count*"
"/home/seanmcl/bin/count")))
(set-process-filter process 'Tmp.filter-fun)))
4) Type C-x
This will cause C-x to show up in the minibuffer. Every time a
line is filtered from count, the C-x flickers in the minibuffer,
sometimes moving a character to the right and then back to the
left.

(I'm going through old bug reports that unfortunately have gotten no
responses yet.)
It looks like this has been fixed in the intervening years -- now you
won't get a "C-x" in the echo area because it's not displayed when
filters are running, apparently.
