This question has rightly been closed for lack of context, which the OP has proved unwilling or unable to attempt to provide. At present, it has two votes for deletion, and I fear it isn't long for the world.
This seems a tragedy to me, not for the loss of the question, but for the loss of rschwieb's answer, which is one of the best I've seen on the site to date.
This sort of thing is certain to crop up again, as it has happened in the past. So, I wonder, what (if anything) can be done to preserve answers despite the questions?
