"Prevent exceptions from leaving destructors." — thank you for providing well known sources that support my point! Although sadly we all have to eat Sutter Meyers bread, at least it explicitly tells you to not worry about the way exceptions are handled during object destruction — by simply avoiding such exceptions. No C++ "bread and butter" I have seen so far goes into depth on this subject.
