Robustness proposal - Overriding SCI presentation

I'm going through the Konqueror robustness practices as George documented 
them, finding the parts that seem to be concrete enough to document, 
checking that they're not already in the Mozilla robustness practices 
(which Johnathan will be covering), and turning them into proposals. 
Here's the first one:

I find that George's overview presumed a familiarity with Konqueror that I 
do not have. Therefore, this draft requires that someone with a clue about 
Konqueror review it and give feedback. George would be optimal, but if 
others have some familiarity, that can work as well. Other sorts of 
feedback is, as always, requested.
