Well, it's certainly far from foolproof, but it takes no time at all to
quickly do and if your problem is completely solved when piggybacking a single

I often find it helpful with logic chips too but that is definately not
foolproof, the bad chip often still affecting the inputs and outputs of the
good chip. Again, it's quick and it sometimes get's me quick results though.
