# this sleep may reduce the number of times it seems to kill wvdial before # ip-up has a chance to start

sleep 15

# wait for ip-up.local to finish, then kill

This seems to work pretty well. Your mileage may vary on how long to sleep to be sure that ip-up has had a chance to start before starting to check whether it has ended.
