I thought about doing it that way and I could do it that way but it
still seems like there should be a way to clean up Queues on my own.
If I did it this way then I guess I'd be relying on garbage collection
when the script ended to clean up the Queues for me.

What if I want to clean up my own Queues?  Regardless of the specifics
of my current design, I'm just generally curious how people manage
cleanup of their Queues when they don't want them any more.
