Interesting that I said I would have to wait a month for the system to lock
up and test this script and it has been exactly a month. In any event, the
script worked and cleared the lock up in a very reasonable time certainly
under a minute. It has now been battle tested. All I had to do was remember
where I put the "kill" button on the remote but it was in an obvious place
and it worked.

Thanks once again to everyone who helped me get this working.
