Comment 9 for bug 314621

I'll implement good old Oscar the Grouch with a 2009 standard name to delete the old records, as I've got some other tables that need pruning too and we don't need to implement this multiple times.

Please confirm the deletion rules. I'm going with 'all CodeImportResult rows created more than 30 days ago, unless they are one of the four most recent CodeImportResults for a branch' unless someone says otherwise. And this is deletion, so don't come crying once the data is gone ;)
