I've used that approach and it works, with at least one potential drawback. If
the user for some reason (perhaps he sees a mistake on the page) clicks the stop
button, then tries to resubmit, the second submit is blocked by the javascript,
but the user has no idea why subsequent submits do not work. So if you use this
technique, your page must also warn the user to reload the page if they need to
resubmit.
