Answer 1

Hi again Matt.
I came up with 2 solutions for dealing with errors.
1)Generate an error message containing words that let the user know the program must be manually exited due to an error
2)Generate a user event in the consumer loop that lets the producer loop know it must quit the program due to error and show a dialog on the way out
To test this I added a Button named error that enqueues a command that  causes the consumer loop to generates an error
Also quiting the producer loop and releasing the queue was generating an error in the consumer loop which caused it to stop
 from the error case.
That works but badly so a better way was to enqueue a quit command to the consumer loop. Done in both updates.
If I were doing the exam I would use the first in the interests of time. Crude but lets the user know.
I attached both versions in case others were interested.
