#10 On session timeout, you should not get an Exception

[Dave Copeland]

Currently, when you submit a query and your session has
timed out, you get a nasty exception. The correct
behavior would be one of the following:

1. Go to a "session timeout" page with a link back home
2. Just go back home and show a "session timeout" message
3. Remember the user's last connection, and reconnect
and execute the query.
