Code review comment for lp:~jontai/openvista-gtm-integration/bug446635

I don't know what routine DDS does or when it's called, so I can't say much. Joel would have to comment.
I was hoping that instead of putting this information in ^TMP, we would put it in ^XTMP with an expiration data of, say, an hour. Then it would get cleared up by the ^XTMP cleanup daemon. ^XTMP is made specifically for these kinds of things. Perhaps that's beyond the scope of what we want right now, though.
