Once again, I find myself thanking Wiser Monks Than I(TM) for sharing their expertise.   This time around it's jcwren, btrott, and merlyn, who gave timely, informative, understandable, and practical answers.

Sometime in the next week or so, I'll update my recent (humble) Code Catacombs entry with changes gleaned from their advice.
