What I've done in the past is have the script do several checks to see if
it's already running to make sure it only starts/stops the database once.
ie: When the backup starts it creates a lock file and shuts down the
database.  Each subsequent time the script tries to run it checks for the
lock file's existence and whether a backup is actually running.  When a
thread is finished and tries to start the database back up it checks to
see if other backup threads are running.  If there are the script exits
quietly.  If not it removes the lock file and starts the database.  I ran
Oracle backups with this for a year and a half with minimal problems.

If you e-mail me off-list I can try to track down a copy of one of my old
scripts and send it to you.
