the way i handled this is with javascript.
on my save button i simply invoke a javascript function on the onclick
event. it checks a javascript page-scoped flag variable to see if save
button has been clicked or not. if it has, then i popup a message
saying "the previous submit is still being processed", otherwise i set
the flag variable and call form.submit(). this works even if they
press the browser "stop" button and then click the save button again.
basically, i'm doing the same thing as you are, but at the client-side
instead of the server side.
maybe there is a better way to handle this problem, but it has been
effective in my production app so far in belaying impatient users...
