Duplicate Delivery Suppression

[Andrew Brink]

What exactly is duplicate delivery suppression?  (Yes, I know it
suppresses duplicate delivery of messages)
Rather, what I want to know is why messages would be duplicated, etc.

I looked in the docs, and wiki a few days ago and didn't find anything
about this, perhaps a wiki post would be helpful.

Thanks!
